About this ranking

Rankings are based on PickNBN's composite internet quality score, which factors in NBN technology type, fibre coverage percentage, FTTP upgrade status, and ABS Census household connectivity rates. Suburbs are sorted by score (highest first), with ties broken by total NBN premises.

Only suburbs with sufficient data quality (score ≥ 3/5) are included. Data sourced from NBN Co, ABS Census, and ACCC broadband benchmarks.
