Australia Statutory late-payment interest
Australia Statutory late-payment interest: no single figure applies. The reason is set out below, cited to the governing instrument. Last checked against the official source on 10 Aug 2026.
Australia fixes no national statutory or late-payment interest rate: court-awarded interest is set per jurisdiction (federal courts: RBA cash rate + 4/6 points half-yearly; each State differs), and no general commercial late-payment statute exists.

What this value means
REFUSAL — jurisdiction-split with no national figure. The Payment Times Reporting Act 2020 is disclosure-only; no commercial late-payment statute fixes a rate. FEDERAL COURTS use half-yearly snapshots of the RBA cash rate (as at 1 January / 1 July) + 4 points pre-judgment / + 6 points post-judgment per practice note GPN-INT — guidance, not a rate-fixing instrument, and the court retains discretion. H2 2026: 8.35% / 10.35% (the RBA hiked three times in 2026 back to 4.35% — do not assume the 2025 cutting cycle continued). STATES DIVERGE: NSW's UCPR mirrors RBA+4/+6; Victoria uses a fixed gazetted penalty rate under the Penalty Interest Rates Act 1983 (10% p.a. since 1 February 2017); other States and Territories differ again. Serving any single figure as 'Australia's rate' would be wrong for most of the country. Retrieval: fedcourt.gov.au 403s non-browser fetchers.
