ASUS RT-AC86U Wi-Fi AC2900 (AI Mesh USB 3.0 Router, AiProtection by Trend Micro, AI Mesh, WTFast Game Accelerator Adaptive QoS, Dual-WAN 3G/4G Support)
Note that this will be a UK model and most likely comes with a UK plug.
EDIT: Thanks to comment by davidl820, it should come with an AU plug
This is only a router.
It cannot replace the NBN vDSL ?
Isn't it redundant that you already have a NBN vDSL with Wifi and you still need to buy another wifi router?
Plus if you are FTTC, there is another NBN device you need to attach to the phone jack outlet so that makes it 3 devices running at the same time.
