Optus vs Telstra vs Vodafone vs TPG: Coverage and Price 2026

Updated: October 2026.

Most Australians overpay for mobile, often for Telstra-grade coverage they only use in the suburbs, so compare Optus, Telstra, Vodafone and TPG, then sign up through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. The networks have converged far more than the ads suggest, and the cheapest path to the coverage you actually need often runs through a brand you've barely heard of. With Black Friday on 27 November, when telco sign-up offers have historically peaked, now is a good time to work out where you really use your phone and which of Optus, Vodafone or Felix Mobile you would port to. Use ShopBack to compare the three sign-up offers on the day you switch, then port to whichever wins. Here's how to match the network to where you really use your phone.

The verdict

For Australian shoppers choosing a mobile plan in 2026, the four major options divide along clean lines. Telstra has the best regional and rural coverage, roughly 99.7% of the population (Telstra), at a 15 to 25% price premium over Optus and Vodafone; if you live or travel in the most remote parts of the country, this premium is worth paying. Optus offers the best price-to-coverage balance for the majority of Australians living in metros and major regional centres, with 5G mature in capitals. Vodafone has closed most of the historical coverage gap, its network now reaches around 98.5% of the population after a 2025 network-sharing arrangement that roughly doubled its coverage area to about 1,000,000 square kilometres (Vodafone), and remains competitive on price, though Telstra still leads in the deepest remote areas. TPG, primarily through its Felix Mobile brand and Vodafone-network wholesale, plus the broader MVNO market (Boost on Telstra, Coles Mobile on Optus, ALDI on Telstra), undercuts the three majors by 30 to 50% on the same towers. The biggest mistake is overpaying for Telstra coverage you never use, or under-paying for an MVNO that throttles you on a remote trip. If you want Telstra-network coverage for less, compare Boost Mobile on ShopBack before you sign up.

Where the price differences come from

ShopBack Australia lists three of the four operators covered here (Optus, Vodafone and Felix Mobile) on ShopBack Australia, so if you switch to one of them, go through ShopBack before you sign up. Australia's mobile market has three physical network operators (Telstra, Optus, Vodafone) and dozens of MVNOs riding on those networks. The wholesale market shape determines pricing more than retail competition does.

Telstra operates the largest mobile network in Australia, covering ~99.7% of the population and a regional and rural footprint materially larger than Optus or Vodafone (Telstra). The Telstra retail brand prices at the top of the market because the regional and rural footprint is genuinely premium infrastructure: dense rural towers, satellite backhaul to remote sites, and commercial 5G coverage in parts of regional Queensland and WA. Telstra wholesale powers Boost Mobile (full retail network access including regional towers), ALDI Mobile, and a handful of other resellers.

Optus operates the second-largest network, covering ~98.5% of the population with a strong metro and major regional footprint (Optus). Optus historically struggled with reputation after public outages and a major customer-data breach in 2022, but the network itself is competitive with Telstra in metro and major regional centres. Optus wholesale powers Coles Mobile, Amaysim, and several others. The price gap between Optus retail and Optus-network MVNOs is the widest of the three.

Vodafone (now operated by TPG Telecom Group) historically had the smallest network footprint of the three, but a 2025 network-sharing arrangement lifted its coverage to around 98.5% of the population, roughly doubling its coverage area from about 400,000 to 1,000,000 square kilometres (Vodafone). It is now close to Optus on population coverage, though its deep-remote footprint still trails Telstra. Vodafone retail prices in the middle of the three majors. The TPG Group also operates Felix Mobile as a Vodafone-network MVNO at the lower end of the market.

TPG is both an MVNO operator (Felix Mobile on Vodafone) and the parent of Vodafone Australia. The TPG retail brand sits between Vodafone and the cheapest MVNOs. iiNet (a TPG-owned brand) sells mobile plans on the Vodafone network.

So the underlying question is: how often are you in deep-remote Australia, and how much do you value contract simplicity over the 30 to 50% saving available on MVNOs?

The networks compared, plan by plan

For any plan tier below at Optus, Vodafone or Felix Mobile, go through the store's ShopBack Australia page before you sign up so part of the cost comes back as ShopBack Cashback.

Feature	Telstra	Optus	Vodafone	TPG / Felix Mobile
Population coverage (approx 2026)	99.7%	98.5%	~98.5%	~98.5% (Vodafone network)
Regional/rural coverage	Strongest	Strong (slightly behind Telstra)	Improved (close to Optus after 2025 expansion)	Same as Vodafone
5G coverage (capitals + regionals)	Mature	Mature	Mature in capitals, growing in regionals	Same as Vodafone
Typical entry plan (small data, 2026)	$45 to $55/month, 30 to 60GB	$35 to $45/month, 40 to 80GB	$30 to $40/month, 40 to 80GB	$20 to $30/month, 30 to 60GB

Customer service rating (industry surveys 2026)	Mid	Mid (post-breach rebuild)	Mid	Variable
Data deprioritisation on MVNO during congestion	N/A	N/A	N/A	Possible
Best for	Regional, rural, remote workers	Metro and major regional, value	Metro and major regional, lower price	Pure price minimisation
Worst for	Pure price-led shoppers	Heavy deep-outback use	Deepest remote/outback use	Heavy roaming travellers
Bundling with home internet (NBN)	Telstra Home (broadband)	Optus Internet	Vodafone NBN	TPG NBN, iiNet NBN

Pricing above is indicative only and changes frequently with promotions; check current rates with each provider (Telstra, Optus, Vodafone, felix mobile). The headline price gap between Telstra and Vodafone retail is roughly 15 to 25% on like-for-like plans, but the gap between Vodafone and an MVNO on the same towers (Felix Mobile) is another 30 to 50%. The cheapest path to Telstra-network coverage outside Telstra retail is an MVNO such as Boost Mobile or ALDI Mobile, which price below Telstra retail while using the same network (Boost Mobile, ALDI Mobile).

A practical note on the Optus 2022 data breach: by 2026 Optus has rebuilt customer trust through plan improvements, network investment, and price competition, but it still carries reputational drag. Some Australian shoppers will pay the Telstra premium specifically to avoid Optus, regardless of the network quality maths. That is a values choice, not a coverage one.

Which network fits your usage

Whichever row below matches, if the carrier is Optus, Vodafone or Felix Mobile the sign-up qualifies for ShopBack Cashback via ShopBack Australia when routed through the ShopBack merchant page. Use the Coverage-Price Map before signing a contract. Answer two questions: where do you actually use your phone, and how much do you value contract simplicity?

Your situation	Best telco	Why
Live or work in rural / remote / outback areas	Telstra (or Boost / ALDI on Telstra network)	Strongest deep-remote coverage
Mining, farming, regional emergency services	Telstra	Coverage and call quality at remote sites
Frequently drive between regional towns	Telstra or Boost	Highway coverage gaps minimised
Metro + drive to major regionals on weekends	Optus, Vodafone, or their MVNOs	Coverage now similar to Telstra in those zones
Pure metro CBD use (Sydney, Melbourne, Brisbane)	Vodafone or Felix Mobile	Best price-to-experience in dense networks
Heavy data user, lots of streaming	Optus (with Optus Sport bonus) or unlimited Vodafone plan	Data caps and entertainment perks
Price-led shopper, modest data needs	Felix Mobile, Coles Mobile, ALDI Mobile	30 to 50% off equivalent major-telco plan
Frequent international traveller (roaming heavy)	Telstra or Optus (day pass)	Mature international day-pass products
Family with 2 to 4 lines	Optus or Vodafone family bundles	Multi-line discounts and shared data
Have an iPhone you bought outright	Any month-to-month SIM	Avoid bundled device contracts
Have an Android budget phone	Any MVNO month-to-month	Bigger savings from lower base plan
Switching from a bundled device contract	Wait until device is paid out	Early termination charges can wipe out new plan savings
First-time Australian SIM (recent move)	Optus or Felix Mobile	Easy onboarding, no postcode credit history needed
Heavy 5G home internet user	Telstra or Optus 5G home internet	5G FWA differs from mobile plan; check separately

The biggest mistake is staying on a Telstra postpaid plan you signed five years ago at $90 a month for 60GB. The 2026 equivalent on Telstra retail is around $55 to $65, on Optus is around $45 to $55, and on Felix Mobile is around $25 to $35 (pricing changes; check current rates at Telstra and felix mobile). Renegotiate or switch.

What switching looks like

ShopBack Cashback via ShopBack Australia is triggered at the sign-up step of the switch, not the port step, so activate ShopBack (or use the ShopBack Chrome extension) before you complete the new carrier's checkout. In practice, switching telco in Australia in 2026 is straightforward: mobile number portability is mandated, the new provider initiates the port, and it usually completes within a few hours (often faster on eSIM) (ACMA). The cost of staying on an outdated plan is the most common easily-fixed household expense.

Three common situations:

• Metro office worker on an older Telstra postpaid plan: Optus retail, or Felix Mobile on the Vodafone network, usually costs less for similar metro coverage (see the indicative ranges in the table above). If you regularly travel to small regional towns, check those places on the coverage map first.
• Worker on remote rotation sites: stay on Telstra-network coverage. Negotiate the Telstra plan down, or move to a Telstra-network MVNO such as Boost Mobile or ALDI Mobile, which use the Telstra network including remote towers (Boost Mobile).
• Family with several lines on one telco: compare an Optus or Vodafone family bundle against separate MVNO lines, since individual MVNO lines can come out cheaper even without a bundle discount.

A practical Cashback note: Optus, Vodafone, Felix Mobile, Boost Mobile and amaysim have ShopBack Australia pages. Go through ShopBack before you complete the sign-up and check the live Cashback offer on the store's ShopBack page.

When this does NOT apply

• You travel for work to the deepest remote or outback sites: even after Vodafone's 2025 expansion, the most remote areas are still safest on Telstra-network coverage (Telstra retail, Boost Mobile, or ALDI Mobile). Verify the exact address against each provider's coverage map.
• You bundle mobile with home NBN: in-bundle discounts often shift the maths. A Telstra mobile + Telstra NBN combo can land cheaper than Felix + a separate NBN.
• You are mid-contract on a bundled iPhone: early termination charges typically claw back the device subsidy. Wait out the contract before switching.
• You need international roaming on a long trip: Telstra and Optus international day passes are mature ($5 to $15 per day in major destinations). Felix Mobile and most MVNOs offer only limited add-on roaming or none.
• You have a credit history issue: Felix Mobile and ALDI Mobile are easier sign-ups than the major postpaid contracts.
• You need physical retail support: Optus and Telstra have national store networks. MVNOs are online-only and may have slower issue resolution.
• You have a Telstra Plus loyalty balance: redemption value can flip the maths if you have built up a significant point balance.
• 5G home internet is part of the decision: 5G fixed-wireless plans are separate from mobile plans and may bundle with mobile at a meaningful discount.

Frequently asked questions

Which Australian telco has the best coverage in 2026?

Telstra has the largest mobile network footprint in Australia, covering roughly 99.7% of the population and a materially larger regional and rural footprint than Optus or Vodafone (Telstra). Optus covers around 98.5% of the population and matches Telstra closely in metro and major regional centres but trails in the most remote areas (Optus). Vodafone now also covers around 98.5% of the population after a 2025 network-sharing arrangement that roughly doubled its coverage area, though Telstra still leads in the deepest remote and outback areas (Vodafone). Whichever carrier you choose, Optus, Vodafone and Felix Mobile are on ShopBack Australia, so go through ShopBack before you sign up and check the live Cashback offer on the store's ShopBack page.

Are MVNOs like Felix Mobile or Boost Mobile as good as the big three Australian telcos?

MVNOs run on the same physical towers as the major networks they wholesale from. Felix Mobile and other TPG-based MVNOs use the Vodafone network. Boost Mobile uses the full Telstra retail network including remote-area towers (Boost Mobile). Optus-network MVNOs include Coles Mobile, while ALDI Mobile runs on the Telstra wholesale network (ALDI Mobile). The voice and data experience is generally similar to the parent network in well-covered areas. Felix Mobile and Boost Mobile are on ShopBack Australia, so go through ShopBack before you sign up and check the live Cashback offer on the store's ShopBack page.

Is 5G worth paying extra for in Australia in 2026?

5G is now standard on most mid-tier and premium Australian mobile plans in 2026 at no significant price premium. Telstra and Optus 5G networks are mature in metro and major regional areas; Vodafone 5G covers most capital cities and regional centres. The practical benefit of 5G over 4G is faster downloads (real-world averages run around 160 to 200 Mbps on 5G versus roughly 50 to 55 Mbps on 4G, with peak speeds well above that) and reduced latency. ShopBack Cashback applies to Optus, Vodafone and Felix Mobile 5G plan sign-ups when the activation is completed through the ShopBack merchant page or ShopBack Chrome extension.

How do I switch mobile providers in Australia without losing my number?

Australian mobile number portability is mandated: your current telco must port your number when you or your new telco request it, and the new provider initiates the port (ACMA). A mobile port usually completes within a few hours, and can be quicker on eSIM. You supply your number, IMEI (or eSIM details), and identity verification. Do not cancel your old plan first; the port process moves the number automatically. Start the sign-up at the ShopBack Australia merchant page for Optus, Vodafone or Felix Mobile so ShopBack Cashback tracks on the port-in activation.

Are Telstra postpaid plans negotiable?

Yes, especially on retention. Telstra customer retention staff have the authority to apply temporary discounts, bonus data, or plan upgrades when you call to cancel. A 5 to 15% discount is common; deeper discounts require a credible threat of port-out to a competitor with a documented offer.

Does Boost Mobile actually get full Telstra coverage?

Yes. As of 2026, Boost Mobile uses the full Telstra retail mobile network, including remote-area towers, with the same coverage map as Telstra retail (Boost Mobile). Boost Mobile prepaid plans typically cost 25 to 40% less than equivalent Telstra retail plans on smaller data tiers. Boost Mobile is on ShopBack Australia; go through the Boost Mobile ShopBack page before you sign up and check the live Cashback offer.

How do I earn cashback on Australian telco sign-ups?

Go through ShopBack to Optus, Vodafone, or Felix Mobile before you sign up. Cashback tracks on eligible new plan activations at the current published rate on each merchant page. Rates vary and change; check the merchant page before signing up.

Which ShopBack Australia partners cover mobile plan sign-ups?

For mobile plan sign-ups, ShopBack Australia lists Optus, Vodafone, and Felix Mobile. Boost Mobile and amaysim also have ShopBack pages; check each store's ShopBack page for the live offer. For handsets to pair with a SIM-only plan, JB Hi-Fi and Amazon Australia list cashback on eligible purchases.

Which Australian mobile plan gives the best cashback value?

Cashback value depends on the plan and the live Cashback offer on each store's ShopBack page, so compare the offers on Felix Mobile, Optus and Vodafone on the day you sign up. Because MVNO base plans already run 30 to 50% below the majors, a Felix Mobile plan is often the lowest-cost option before Cashback.

Can I use a telco sign-up bonus with ShopBack Cashback?

Telco promotional bonuses (extra data, discounted first months, bill credits) generally still work with ShopBack Cashback because Cashback tracks on the plan sign-up itself. Go through ShopBack to Optus, Vodafone, or Felix Mobile before you sign up.

How much cashback can I earn on a mobile plan sign-up through ShopBack?

Cashback depends on the live offer on each store's ShopBack page, and offers change, especially around sale windows. Check the live Cashback offer on the Optus, Vodafone and Felix Mobile ShopBack pages before signing up.

When is the best time to switch mobile plans with ShopBack cashback?

Cashback rates on Australian telco sign-ups often rise around EOFY (June), Black Friday (late November), Boxing Day (December), and new financial year cycles. If your port-out lines up with one of these windows, go through ShopBack before you sign up on Optus, Vodafone or Felix Mobile. Set a calendar reminder for your current contract end date and check ShopBack rates 2 to 4 weeks ahead.

Does ShopBack cashback apply on existing telco plan renewals?

ShopBack cashback on telcos typically tracks on new activations and ports, not on renewals of an existing plan. Some merchants offer cashback on selected postpaid upgrades or SIM top-ups during promo periods. Check the terms shown on the Optus, Vodafone, and Felix Mobile merchant pages before proceeding.

Should I port to Optus, Vodafone or Felix Mobile before Black Friday 2026?

It depends on where you use the phone. Optus suits metro and major regional users who want a mature network, Optus Sport and a national store footprint. Vodafone suits metro users who want a slightly lower price on a network that now covers around 98.5 percent of the population. Felix Mobile suits pure price minimisers in capital cities who can live without roaming day passes, because it rides the same Vodafone towers for 30 to 50 percent less. If your current plan ends before late November, waiting for the Black Friday offers is usually worth it. Check ShopBack before you complete the sign-up so the cashback tracks on the port-in.

Why is Boost so much cheaper than Telstra?

Boost is cheaper than Telstra because Boost resells wholesale access to the Telstra network as mostly prepaid plans, so it skips much of the retail cost Telstra carries, such as stores, contracts, handset repayments and bundled extras. The towers are the same, so the price gap comes from the retail model, not a weaker network. Boost suits prepaid users who want Telstra-network coverage, including regional areas, without a contract. Telstra retail suits people who want postpaid billing, in-store support, handset repayments or bundled perks. City users chasing the lowest price can also compare other resellers in our MVNO comparison. Check the cashback offer on the ShopBack Boost Mobile page and activate it before you sign up.
