FAQ
Does Optus have promo codes? Optus runs plan promotions and sign-up offers on the Optus website, especially around EOFY, Black Friday, Cyber Monday, and Boxing Day. These sit on the plan landing pages rather than as generic coupons. Before you sign up, start from the ShopBack Optus page so part of what you pay comes back as Cashback.
How do I get an Optus discount code that works? Any active Optus promotional pricing appears on the plan pages at optus.com.au. Third-party coupon aggregators often list expired offers. For new sign-ups, going through ShopBack before you sign up on the promotional plan price means part of the cost comes back.
When does Optus run plan discounts? Optus refreshes plan offers throughout the year, with heavier promotional windows around EOFY at the end of June, Black Friday and Cyber Monday in late November, and Boxing Day on 26 December. Bonus data allocations, waived first-month fees, and bundled entertainment perks are the mechanics most often used.
How do I save on Optus? Compare SIM-only against contract plans, right-size the plan to actual data use, watch for EOFY and Black Friday windows, consider bundling mobile with home internet if Optus is the household provider, and start new sign-ups from ShopBack so part of the cost comes back as Cashback.
Is Optus SIM-only cheaper than an Optus contract plan? SIM-only plans do not include the cost of a handset spread over 24 or 36 months, so the monthly bill is lower than a comparable contract plan. Shoppers who already own their phone or plan to keep it for the next few years save the most on SIM-only. Contract plans make sense when the shopper wants a new phone as part of the deal.
What is Optus SubHub? Optus SubHub is a single-bill service that lets Optus customers add and manage supported subscriptions from one place. Supported services, any multi-service discount and any plan credits change over time, so check the current details on the Optus SubHub page.
Is Optus cheaper than Telstra and Vodafone in Australia? The cheapest plan varies by data allowance and inclusions at any given time. Optus, Telstra, and Vodafone Australia rotate promotional pricing on SIM-only and contract plans, and smaller providers such as TPG and Amaysim run on the same networks with different price points. Comparing plans by monthly cost per gigabyte at the time of purchase is the most useful test.

How is ShopBack different from coupon or promo code sites? ShopBack is a Cashback app and website, not a coupon site. Cashback comes back as real, withdrawable cash to your ShopBack account.

With ShopBack, you start from the store's page before you pay and no code is needed.

Optus does publish promotional codes and sale prices, but codes often carry expiry windows, category exclusions, or single-use restrictions that reduce or void the saving at checkout.

How do I save on Optus without a promo code? Open the ShopBack Optus page or the ShopBack browser extension before you sign up. Part of what you pay comes back as Cashback, no code required.
