Cheapest by speed tier

Ranked on price alone. Nothing is promoted. Every card hands off to the provider's own page. Intro prices are listed apart: today's intro deals.

By place

A page for every Australian postcode, with the cheapest plan on each tier and the address check.

NBN prices do not change by postcode, but what your line can carry does. Each postcode page says both plainly: Sydney 2000, Melbourne 3000, Brisbane 4000, Adelaide 5000, Perth 6000, Broken Hill 2880. The postcode directory lists every postcode with every suburb in it, by state.

Not getting the speed you pay for?

Your evening speed test against what the ACCC measured for each provider on your tier.

The ACCC's Measuring Broadband Australia programme measures busy-hour download as a share of plan speed for the large providers. Enter your provider, tier and a speed test to see how it compares and which providers were measured delivering more, each with its cheapest plan on that tier. Paying too much? The bill check takes what you pay and your tier and places it among every quotable plan on that tier.
