I switched to Iinet in 2009 in Sydney for my business and my monthly bill dropped around 85% . I moved to Qld in 2013 but was unable to connect to Iinet until 2016. Their service is excellent and I have only experienced a few periods of dropouts which have been attended to promptly and have been found to be in the NBN node.
I highly recommend Iinet for price and service.
If there was no Iinet and the other smaller players in the market only Telstra and Optus imagine what you would be paying for your data service
