its always worth having a look at options outside of the NBN, especially if your only NBN options are FTTN or fixed wireless.
Dependant where you are located, there are more and more independent fixed wireless networks operating (and growing a lot thanks to being a better option than the NBN).
Over on this side of the world (WA) there are two that I know of, Node1 and Pentanet.
I have been with Node1 for a couple of years, I honestly wouldn't have NBN if they were giving it away free. I have a small sat dish on my roof that has 'line of site' to a Node1 tower...and thats it.
Im on an older (grandfathered) plan now, $89 per month, unlimited downloads/uploads, at whatever max speed I can get.
I currently average out at around 170Mbps down and 140Mbps up, with a ping of around 10ms (24hrs a day, every day, no peak hours congestion...ever, even with so many people currently working from home). In the past couple of years I can count the amount of dropouts Ive had on one hand.
My address is serviced by NBN FTTN - that wouldnt even come close to what I get now.
Local company, local support, great service and fantastic internet.
Dont just follow the sheep and go down the NBN route. Have a look at what else is available. Its sometimes a far better option.
