With the launch of NBN Gigibit plans I know a few people on OzBargain have been waiting for a decent deal to come up for the ASUS RT-AX88U, (I was one) the Sydneytec eBayStore have it for $468.06 after applying eBay Plus Coupon code PARTY21
This looks to be the best price since the Mwave/Bing Lee deal and ASUS Christmas promotion back in December 2019.
Merlin has stopped firmware updates on this until asus fix their stuff afaik.
