A lot of us buy deals on kogan anyway, and there are two ways you can stack to earn 2.5 Qantas points per $1 spent.
Step 1. Earn 0.5 point per $1 spent on eligible products once you've linked your Frequent Flyer account to your Kogan.com account.
Step 2. Earn 2 points per $1 when you click through from Qantas Shopping each time you shop.
Hope it helps!
Just as an FYI - the T&C's for clicking through the Qantas shop - no points when using gift cards or credits (such as Kogan card rewards).
"Qantas Points will be earned on the price of the goods only and not on any GST, delivery charges or taxes. Qantas Points will not be earned on the purchase of a gift card; where a gift card or voucher is used as a payment method (whether for full or part payment); or where a coupon or discount code is used (unless that coupon or discount code is valid and listed on Qantas Shopping). Qantas Points will not be earned on cancelled, amended or refunded transactions. Individual retailer terms and conditions apply."
