Google Nest Wifi - 2 Pack is on sale at Bing Lee. This is $100 off the usual price (25%) and cheapest I've seen. I bought this at Officeworks for another 5% off at $284.05. The secondary wifi point also acts as a Google Nest Mini.
The reason why I bought this was to upgrade my old Google Wifi so that it could handle 1080p desktop mirroring on the Chromecast without buffering/stuttering. The reason why you would want this over a conventional router is if you had a large house or you have 60 smart home devices like me. Most conventional routers (even the $400 ones) can't handle more than 30 devices, you need a modern router like this to be able to handle more.
Nice deal, I paid $399 for mine (RRP).
Has ~50 devices connected, runs like a dream. Only down side is can't adjust things via a PC, must be done via Google Home or Google WiFi app (or BlueStacks, etc). Otherwise it's brilliant.
