I live in an area where there are limited options due to the fibres installed by Telstra. Exetel is the only provider I was able to find that could offer an unlimited broadband plan.
Pros: My experience is that the connection is usually rather fast and always reliable.
Cons: There is a long waiting period for activation. Furthermore, when I tried to change payment methods I found that the customer service I received was fairly average.
At the end of the day, I am thankful for the fact that I have a reliable and relatively fast connection with unlimited download, but would suggest improvements for customer service, particularly because some customers are paying more based on where they live.
