Cashback for Bills in Australia (2026): Insurance, Broadband, Mobile and Energy
Travel bookings are the obvious cashback play. Bills are where a lot of Australians quietly miss the bigger dollar wins.
Updated March 20, 2026: I checked current ShopBack Australia finance pages, the TopCashback Australia sign-up page, and live TopCashback retailer pages for categories like broadband and mobile before writing this. Cashback rates move constantly, so the important thing here is the process and the kinds of merchants available, not the assumption that every number will stay the same.
Quick navigation
Quick Verdict
Best overall starting point: ShopBack. Its finance category currently shows meaningful cashback examples across electricity/gas comparison, insurance comparison, and broadband comparison.
Best extra kicker: TopCashback AU. The current public sign-up page still advertises a $25 sign-up bonus after $25 spend for eligible new members by December 31, 2026.
Best bill categories: broadband, SIM/mobile, energy comparison, and insurance comparison. These are often worth more than the tiny cashback rates people chase on groceries.
Biggest mistake: treating cashback like a discount instead of a tracked referral path. Wrong coupon codes, mobile apps, refunds, changes, and privacy tools can kill the payout.
A lot of cashback content focuses on travel or fashion because it looks more exciting. Bills are less fun, but they are often where the bigger, more rational cashback wins live.
Think about it:
- an insurance or broadband conversion can be worth far more than a random shopping click
- these are expenses you were going to review anyway
- the dollar amounts are often fixed and visible, which makes the value easier to judge

Current Cashback Examples I Checked
| Platform | Current example | Why it matters | Big catch |
|---|---|---|---|
| ShopBack AU | Finance pages currently showed Compare The Market up to $300, Compare Electricity and Gas up to $160, Broadband Comparison $90, and Superloop $90. | This is why bills are worth checking. One tracked switch can beat months of tiny shopping cashback. | Category pages are broad. You still need to read the merchant terms before you assume a specific product or switch will qualify. |
| TopCashback AU signup | Public signup page currently advertises a $25 sign-up bonus after $25 spend for eligible new members, valid until December 31, 2026. | That makes TopCashback more interesting even before the retailer-specific cashback starts stacking. | You need to sign up through the eligible page and hit the spend threshold within 180 days. |
| TopCashback AU retailer pages | Aussie Broadband up to $60, Mate Internet up to $25, Mate Mobile $15, Everyday Mobile from Woolworths up to $30 on the live pages I checked. | Broadband and mobile are some of the cleanest “household bill” cashback categories in Australia right now. | Most pages exclude mobile-app purchases, unapproved coupon codes, and non-new-customer transactions. |
The Best Bill Categories for Cashback in Australia
These are the categories I would check first before spending energy on smaller, noisier cashback plays:
- Broadband: one of the best bill categories because the cashback is often fixed and meaningful.
- Mobile plans: prepaid and SIM-only offers can be surprisingly decent, especially for new customers.
- Energy comparison: the comparison-service style cashback can be much bigger than direct merchant cashback.
- Insurance comparison: another high-value category where one tracked conversion can be worth real money.
What I would not obsess over is tiny category cashback where the product price or plan quality is not competitive. Bills are only worth chasing if the underlying switch still makes sense.
ShopBack AU: Best for Big Compare-Style Bill Cashback
ShopBack’s Australian finance pages are one of the clearest reminders that cashback is not just about shopping. On March 20, 2026, the live finance category was showing examples like Compare The Market up to $300, Compare Electricity and Gas up to $160, Broadband Comparison $90, and Superloop $90.
That is exactly why this category matters. If you are reviewing a bill anyway, one tracked comparison or switch can be worth more than a year of casual cashback clicking on smaller purchases.
ShopBack is also the easier recommendation for most people because the interface is simple and the category structure is obvious. It feels less fussy than manually hunting through lots of individual retailer pages.
Where ShopBack is strongest for bills
- comparison-led energy cashback
- insurance comparison offers
- broadband switching offers
TopCashback AU: Best for Broadband/Mobile Detail and the $25 Signup Bonus
TopCashback AU becomes much more interesting once you realise it is not just the retailer cashback you are getting. The current public signup page is still advertising a $25 sign-up bonus after $25 spend for eligible new members through December 31, 2026.
Then on top of that, the retailer pages I checked showed examples like Aussie Broadband up to $60, Mate Internet up to $25, Mate Mobile $15, and Everyday Mobile from Woolworths up to $30.
That makes TopCashback particularly good for people who are willing to check merchant-level pages before switching. It is less “set and forget” than ShopBack, but arguably more rewarding for careful users.
TopCashback AU is strongest when
- you want the new-member bonus plus retailer cashback
- you are comparing broadband and mobile providers
- you are willing to read exclusions before buying
How I’d Actually Stack Bill Cashback
- Compare the real plan first. Cashback should never rescue a worse product.
- Check both ShopBack and TopCashback AU. Bills are one of the few categories where it is worth doing both.
- Read the merchant exclusions. New-customer rules matter a lot in broadband, mobile, and energy.
- Use one clean browser session. No app hopping, no ad blockers, no VPN, no random coupon codes.
- Remember the signup bonus layer. TopCashback’s current $25 new-member bonus changes the math if you are new.
This is exactly the same logic I use on my broader travel cashback post. The category changes, but the process is basically identical: best base deal first, cashback second, clean tracking path always.
What Usually Kills Bill Cashback
- Using the retailer app. Several TopCashback mobile and broadband pages explicitly exclude app purchases.
- Applying coupon codes not shown on-platform. This can void eligibility.
- Not being a true new customer. A lot of bill cashback only works for new customers.
- Using privacy tools that break tracking. VPNs, ad blockers, and some browsers can interfere.
- Changing, cancelling, or partially refunding. These categories are heavily tracked and often strict.
Best Simple Setup
Use ShopBack for the broad finance-category view, then check TopCashback AU before any bigger broadband, mobile, or insurance switch.
Frequently Asked Questions
Is cashback on bills actually worth it in Australia?
Yes. Broadband, insurance comparison, and energy comparison are some of the most rational cashback categories because the dollar amounts can be meaningful and the underlying purchase is a recurring expense you probably review anyway.
Which cashback site is better for bills?
ShopBack is easier for broad category discovery. TopCashback AU is better if you want a new-member bonus and merchant-level detail for broadband and mobile.
Can I use coupon codes and still get cashback?
Only if the merchant page explicitly allows the code. Otherwise assume it can void the cashback.
What’s the biggest mistake people make?
Choosing the cashback instead of the best plan. Cashback should improve a good switch, not justify a bad one.
Bottom line: bills are one of the best cashback categories in Australia, but only if you compare the actual plan first and protect the tracking path properly.
