HECS-HELP — Understanding Indexation
HECS-HELP debt does not accrue interest, but is indexed to the Consumer Price Index (CPI) each 1 June. The 2023 indexation rate of 7.1% was the highest since 1990 and increased many students' debt by thousands of dollars, reigniting debate about HELP debt reform.
Repayments are compulsory once you exceed the threshold ($54,435 in 2024-25) and are collected through your tax return. You can also make voluntary repayments at any time through myGov/ATO, but there is no longer a bonus for doing so.
