iPhone 16 vs Samsung Galaxy S25 in Australia 2026: Total Cost Outright vs 24-Month Plan

Two flagships, two payment models, one question: which combination costs least over the 24 months you actually own the phone? For Australian buyers choosing between the iPhone 16 and the Samsung Galaxy S25 in 2026, the "cheaper" answer depends less on which phone and more on how you pay for it.

The verdict

For most Australian buyers, buying outright and pairing with a SIM-only plan is AUD 500 to AUD 900 cheaper over 24 months than a bundled Telstra, Optus, or Vodafone phone plan. At like-for-like storage, the iPhone 16 and Samsung Galaxy S25 are priced within AUD 20 of each other at the base tier, so the phone itself is not the deciding cost factor. The plan is.

Bundled carrier plans win in three specific cases: (1) when the carrier runs a large device-credit promotion (EOFY, Christmas, back-to-school in January) that effectively subsidises the handset; (2) when the buyer cannot access 24-month interest-free finance from Apple, JB Hi-Fi (via Latitude), or Harvey Norman; and (3) when the buyer values a single bill and does not have cash for an outright purchase.

Retailer notes:

• Apple.com.au offers the widest storage/colour range on launch and 24-month interest-free via Apple Payments. Trade-in usually within AUD 50 of best market price.
• JB Hi-Fi rarely price-matches formally but discounts at the counter, particularly on Samsung stock. Bundled cases and screen protectors sometimes discounted 30 to 50 percent with handset.
• Officeworks offers its 5 percent price beat on qualifying competitor prices, though Apple stock is often excluded from cross-retailer beats. Business ABN pricing sometimes 3 to 5 percent below retail.
• Samsung.com.au typically leads the market on Samsung trade-in credits at launch (often AUD 100 to AUD 300 above competitors on same-generation trade-ins).

Samsung sale discounts are structurally deeper than Apple sale discounts. Samsung typically drops 15 to 20 percent within 3 to 6 months of launch; Apple typically drops 5 to 10 percent in the same window.

24-month plan total cost: Telstra, Optus, Vodafone

Indicative 2026 monthly costs on medium-data (roughly 100 to 200 GB) plans with a bundled iPhone 16 128GB or Galaxy S25 128GB, 24-month term. Rates vary by promotion; treat as reference.

Carrier	Monthly plan	Monthly device instalment (24 mo)	Monthly total	24-month total
Telstra Upfront	AUD 75 to 89	AUD 58 (iPhone 16 128GB)	AUD 133 to 147	AUD 3,192 to 3,528
Optus Choice Plus	AUD 65 to 79	AUD 58 (iPhone 16 128GB)	AUD 123 to 137	AUD 2,952 to 3,288
Vodafone Infinite	AUD 55 to 75	AUD 58 (iPhone 16 128GB)	AUD 113 to 133	AUD 2,712 to 3,192

Same for Samsung Galaxy S25 128GB (device instalment identical at AUD 58/month across all three, since RRP is the same).

Outright + SIM-only comparison:

• iPhone 16 128GB outright at AUD 1,399 (or Boxing Day at AUD 1,249) + SIM-only Vodafone at AUD 45/month for 24 months = AUD 1,249 + AUD 1,080 = AUD 2,329 total.
• iPhone 16 128GB via Vodafone 24-month plan at AUD 113/month = AUD 2,712 total.
• Outright saves AUD 383 over 24 months on Vodafone. Against Telstra Upfront at AUD 133/month = AUD 3,192 total, outright saves AUD 863.

The gap is larger than most buyers estimate. The bundled plan's convenience comes at a real cost.

Which retailer + carrier stack is cheapest

For the Australian buyer who wants the lowest 24-month total cost, the answer follows a hierarchy:

1. Best case (AUD 2,000 to 2,400 total for 128GB flagship + 24-month connectivity): Buy iPhone 16 or Galaxy S25 at Officeworks or JB Hi-Fi during Boxing Day, Click Frenzy, or EOFY (typical discount AUD 150 to 250 off RRP). Pair with a Telstra prepaid or a Kogan Mobile / TPG SIM-only plan at AUD 25 to 40 per month.

2. Middle case (AUD 2,400 to 2,800 total): Buy outright at RRP through Apple.com.au or Samsung.com.au. Pair with Vodafone Infinite or Optus Choice Plus SIM-only at AUD 45 to 55 per month.

3. Convenience case (AUD 2,700 to 3,500 total): Bundled 24-month plan through Telstra, Optus, or Vodafone. Higher total cost but single bill, upgrade path at 24 months, and no upfront capital outlay.

The AUD 700 to AUD 1,000 gap between best-case and convenience-case is meaningful. For couples buying two phones simultaneously, that gap doubles to a full trip's worth of savings.

Trade-in credits: how they change the math

Trade-in credits materially shift the outright-vs-bundle calculation.

Apple trade-in program. As of 2026, indicative credits: iPhone 13 128GB (AUD 350 to 450), iPhone 14 128GB (AUD 450 to 550), iPhone 15 128GB (AUD 600 to 700). Applied instantly to a new iPhone 16 purchase.

Samsung trade-in program. Indicative credits: Galaxy S22 128GB (AUD 200 to 300), Galaxy S23 128GB (AUD 300 to 400), Galaxy S24 128GB (AUD 450 to 550). Applied instantly to a new S25 purchase.

Carrier trade-in. Telstra, Optus, and Vodafone often offer AUD 100 to AUD 300 above Apple/Samsung's own trade-in when bundled with a new 24-month plan. This narrows the outright-vs-bundle gap.

Worked example: iPhone 14 128GB trade-in on a new iPhone 16 128GB.

• Apple direct + SIM-only: AUD 1,399 outright minus AUD 500 trade-in = AUD 899 phone + AUD 1,080 (24 x AUD 45 Vodafone SIM) = AUD 1,979 total.
• Telstra bundle + carrier trade-in: AUD 3,300 total minus AUD 700 carrier trade-in credit (over 24 months) = AUD 2,600 total.

Outright still wins by AUD 620, but the gap narrows from AUD 1,000 to AUD 620 once the carrier's premium trade-in kicks in.

Where each phone actually differs (beyond price)

iPhone 16 wins on:

• iOS ecosystem lock-in (AirPods, iCloud, iMessage, Apple Watch, Mac)
• Resale value: 2-year-old iPhones retain roughly 50 to 60 percent of RRP
• 5+ years of software updates typical
• Best-in-class camera colour science for stills

Samsung Galaxy S25 wins on:

• S Pen (Ultra only), telephoto zoom, folding option (Fold and Flip line siblings)
• Better third-party charger and accessory ecosystem (USB-C standard is deeper)
• One UI customisation depth
• Samsung Health integration and DeX desktop mode

Rough parity on: Battery life, screen brightness, day-to-day speed, camera performance in good light.

For most Australian buyers, the tie-breaker is either ecosystem (existing Apple products or existing Samsung products) or specific features (S Pen, folding form factor). Cost is not usually the deciding factor between the two flagships themselves.

Frequently asked questions

Is it cheaper to buy an iPhone 16 or Samsung S25 outright or on a 24-month plan in Australia? Buying outright and pairing with a low-cost SIM-only plan is typically AUD 500 to AUD 900 cheaper over 24 months than a bundled carrier plan on Telstra, Optus, or Vodafone. Bundled plans win only when the carrier runs a strong device-credit promotion or when 24-month interest-free financing is unavailable.

What is the 2026 outright price of the iPhone 16 and Samsung Galaxy S25 in Australia? iPhone 16 128GB launches at AUD 1,399 through Apple Australia; the Pro Max 256GB sits near AUD 2,199. Samsung Galaxy S25 128GB launches near AUD 1,399; Galaxy S25 Ultra 256GB sits near AUD 2,199. JB Hi-Fi and Officeworks typically match these prices, with occasional discounts at EOFY, Click Frenzy, and Boxing Day.

Which carrier plan is best paired with an iPhone 16 or S25 in Australia 2026? For most users, a Telstra, Optus, or Vodafone SIM-only plan at AUD 55 to AUD 85 per month paired with an outright phone gives the lowest total cost. Telstra has the widest coverage, particularly regional. Optus and Vodafone are typically 15 to 25 percent cheaper. TPG and Boost offer sub-AUD 40 plans for lighter users.

Do I earn cashback on iPhone 16 or Samsung S25 purchases through ShopBack? Cashback availability depends on the retailer. Apple and Samsung mobile devices at JB Hi-Fi, Officeworks, Apple.com.au, and Samsung.com.au have varying cashback rates. Carrier plans at Telstra, Optus, and Vodafone often have generous new-plan activation cashback. Check the merchant page for current rates.

Are there hidden costs in a 24-month carrier plan? Yes. Common ones include minimum plan-term contracts, pro-rated exit fees, network downgrade restrictions, and lost device-credit if switching plans. Read the critical information summary before signing.

How much can I save by trading in my old iPhone or Samsung phone? Trade-in for a 2 to 3 year old iPhone (iPhone 13 or 14) at Apple, JB Hi-Fi, or a carrier ranges from AUD 200 to AUD 700. Samsung S22 or S23 ranges from AUD 150 to AUD 600. Carrier trade-ins bundled with a new plan often offer AUD 100 to AUD 300 more than outright cash offers.

Key takeaways

• Outright + SIM-only saves AUD 500 to AUD 900 over 24 months vs a bundled carrier plan.
• iPhone 16 and Galaxy S25 are within AUD 20 at like-for-like storage; the phone is not the deciding cost factor.
• Sale windows matter more than retailer choice: EOFY, Click Frenzy, and Boxing Day discounts of AUD 150 to AUD 250.
• Trade-in credits narrow but don't close the gap in favour of bundled plans; outright still typically wins.
