Saw this on Facebook ad - been waiting for a code that works for Fixed Wireless for family as most of their deals have been NBN only.
I've been with them for 6 months in South Australia on their 100mbit plan, and its never had slowdowns (Peak, rain, wind) - although YMMV as I've seen some bad reviews also depending on your location.
You can BYO router, the one they provide is pretty rubbish, replaced it almost immediately. Don't forget to pick a random referral code if you do join for $25 gift card.
For what it's worth, had Uniti Fixed Wireless for around a year. Only could get the 50mbit plan but it was rock solid.
