Approximately 3 million students and graduates are facing a combined $1 billion increase in their HECS debt this Monday, as annual indexation of 2.8% takes effect. While these debts do not accrue interest, they are adjusted annually based on inflation or the wage price index to preserve their real value.
The current system faces criticism because compulsory repayments, while collected throughout the year by the tax office, are not deducted from the debt balance until after a taxpayer files their return. This means the indexation is applied to the full debt amount before the year’s repayments are credited, a process independent MP Monique Ryan has labeled a “broken system.”
The Case for Reform
New costings from the Parliamentary Budget Office suggest that shifting the indexation date from 1 June to 1 November would allow compulsory payments to be factored in first. Such a policy change could save graduates more than $3 billion over a decade. In the first year alone, students would see $58 million in savings, with that figure projected to grow to more than $150 million annually by 2035-36.
Did You Know?
Unlike HECS debts, which are indexed on a single date, various social security payments are indexed at different times throughout the year. For instance, the aged pension and disability support payments are indexed on 20 September, while Jobseeker is indexed biannually in March and September.
Policy Implications and Potential Paths
The proposal highlights a tension between government revenue and the financial pressure on young Australians. While the change could save graduates billions, it would also result in $1.2 billion in forgone revenue for the government’s underlying cash balance over a four-year period.
Expert Insight:
The debate underscores the complexity of modern fiscal policy. While the government has previously moved to cap indexation at the lower of inflation or the wage price index and implemented a 20% debt reduction, this latest call for reform targets the structural mechanics of the loan system itself. Moving the indexation date would represent a fundamental shift in how the government manages the timing of debt relief versus budgetary intake.
Education Minister Jason Clare has acknowledged that there is “more work to do” regarding the student loan system. Looking ahead, the government may face continued pressure to align the timing of debt accounting with the lived reality of those repaying their loans. Whether policymakers prioritize immediate budgetary stability or further relief for graduates remains a point of significant debate.
Frequently Asked Questions
Why does HECS debt increase if it doesn’t have interest?
HECS debts are indexed annually based on inflation or the wage price index to ensure the government maintains the “real value” of the money originally lent.

How much would graduates save if the indexation date changed?
Graduates could save more than $3 billion over a decade if the indexation date were moved from 1 June to 1 November.
What has the government done to address student debt recently?
In December 2024, the government changed rules so that debts increase by whichever is lower between inflation and the wage price index. They also committed to a 20% reduction in HECS debts as part of a 2025 election promise.
Do you believe the timing of HECS indexation should be adjusted to better reflect when repayments are made?
