Other states and territories

Place names from Matthew Proctor's Australian postcodes dataset, rebuilt 2026-10-25; the lead name is the locality the postcode is usually known by. Nothing on this page is a price. All states · How prices are collected

Open pricing means Australians can be better informed, and save more.

Most comparison sites show a fraction of the market: the providers that pay to be listed. OpenStream tracks every NBN brand on NBN Co's register, 149 NBN brands on the register, with 431 priced NBN plans re-read every hour. Nothing is promoted, every price links to the page it came from, and the whole dataset is free to download.
