Stack a $5 bonus cashback on top of TopCashback's already-boosted Amazon AU rates when you spend $30+ in one transaction today.

Just activate the bonus first, then click through to Amazon AU and shop as normal — you'll earn the $5 on top of your usual cashback, across all categories
Huge stacking potential: pay with gift card balance, grab a first Subscribe & Save order, or even shop overseas sellers via Amazon AU and it still counts
Two catches worth knowing: clear your cart before clicking through, and skip the gift card/voucher/Prime subscription purchases
Offer expires tonight (29/09/2026) at 11:59pm AEST, and tracking can take up to 7 days to show in your account

If you're already planning an Amazon haul for Prime Big Deals Day, this is basically free money for a purchase you were making anyway — just don't forget to activate first.
