Best cash price I've found for the STR-AN1000 listed in Australia - It was cheaper (if you consider the gift cards here) however.
There are other options such as the Yamaha RX-V6A for sale at Hardly Normal too which I almost jumped on personally $984 after taking into account HN Gift card.
I don't think West Coast Hifi do any form of cashbacks unfortunately, I will update if someone posts that they do.
Coupon is for $100 off any purchase over $1000 too if that's helpful
Nice find, how does this compare the pre-covid 1080 model?
