With Aussie broadband you can also get a faster connection with FTTP 150+ etc.
They come highly recommended, although, I'm yet to try them myself.
I have Optus unlimited with Fetch TV, $100 for 100/40 on FTTN and it's unreliable as all hell with a lot of dropouts, but I'm moving soon to a place with FTTP and I'm hoping using a new router (instead of the terrible Optus one) with the built in modem of the FTTP connection will fix that problem. Also, if you have a bit more cash to splash you could just get a cheaper connection, 50/20 unlimited is $80, and also get a smaller connection with Aussie, maybe 150gb of 100/40 for gaming. This is possible using one of the other 4 ethernet ports on the NBN box on your wall, I phoned them to check and they can do it month by month with no lock in contract (if I have holidays I'm gonna try it).
If I had the chance to choose again, I'd go with Aussie. But that's based on others recommendation not my own personal experience.
Good luck mate :-)
