The company that made 100 mbps plans the norm in Singapore, Indonesia and New Zealand is now launching in Australia. At 59.99 for a 100mbps line, it will be the cheapest 100mbps plan in Australia. Not to mention a lot cheaper than some ADSL plans and some lower speed NBN plans from other providers that have download limits. They also have a MyRepublic Gamer plan for 69.99. Not sure what different but possibly to do with low network latency (+static IP).
Not sure how they will manage the $59.99 price with the NBN's CVC pricing model on top of the AVC charge but the CVC pricing model is being overhauled soon hopefully
I had Telstra cable and it actually exceeded speeds. Got 130-140Mb/s down and didn't have congestion ever. I guess it's what area you live in.
