Australia’s mortgage cliff was the wave of fixed-rate home loans written during the pandemic at record-low rates that reverted to far higher variable rates as the Reserve Bank lifted the cash rate from May 2022. The heaviest roll-off ran through 2023, when roughly 880,000 loans transitioned, and its effects on household budgets continue wherever low fixes have since expired.
This guide explains where the cliff came from, what happened when the fixes expired and how brokers can help clients manage the repayment step-up. It is written for Australian mortgage brokers advising clients who locked in pandemic-era rates or took over those loans since.

Where the Mortgage Cliff Came From
The cliff describes fixed-rate home loans written at historically low interest rates during the pandemic, which reverted to much higher variable pricing as the Reserve Bank of Australia’s tightening cycle took hold from mid-2022.
During the pandemic the RBA cut the cash rate to a record low of 0.10%, holding it there from November 2020 until May 2022. Fixed-rate home loans below 2% appeared across the market, and hundreds of thousands of borrowers locked them in, entering the housing market on repayments that felt permanently affordable.
The fixed terms were always temporary, typically two to three years. What changed was the rate environment waiting on the other side.

What Happened When the Fixes Expired
The RBA began lifting the cash rate in May 2022 and took it to 4.35%, where it stood after the August 2026 meeting. Borrowers rolling off pandemic-era fixes moved from rates near 2% onto variable or revert rates set by their lenders at levels far higher, so repayment step-ups landed hard and fast. Each lender sets its own variable and revert pricing individually.
The RBA estimated around 880,000 fixed loans rolled off during 2023 alone, which was the sharpest single year of the transition. Later expiries faced smaller gaps because the difference between old fixed rates and current rates narrowed over time.
The Impact on Households and the Economy
For affected households the mechanics were blunt: same loan balance, materially larger required repayment, often several hundred dollars more each month. That step-up pushed many budgets from comfortable to stretched, and indicators of mortgage stress, including rising arrears on recently converted loans, followed the roll-off closely.
At the economy-wide level, reduced consumer spending absorbed part of the shock, while arrears and distressed sales stayed comparatively contained by historical standards. The cliff strained households unevenly rather than uniformly, which is exactly why broker conversations needed to be case by case.
How Brokers Can Help Affected Clients
- Model the new repayment before expiry, using the lender’s actual revert rate, so the client sees the change in dollars months ahead rather than on statement day.
- Compare refinancing early: a refinancing review before the fix expires often finds sharper options than the default revert rate, though serviceability is tested at today’s buffers either way.
- Raise hardship options without waiting: lenders can vary loans for borrowers under pressure, and clients needing independent financial counselling can be referred to the National Debt Helpline on 1800 007 007.
- Document everything: the advice given, options presented and the client’s decision protect both parties if circumstances deteriorate later.
What Remains Relevant Now
The steepest part of the cliff is behind the market, but the topic stays live in three ways: late-expiring fixes are still converting, clients who scraped through 2023 and 2024 remain exposed to any renewed rate pressure, and the episode reshaped how lenders assess new borrowing. For brokers, the practical legacy is a client base that now expects proactive rate reviews instead of silence between fixed-term expiries.
Next Step: Audit Your Book for Remaining Fixes
Run a report this month listing every client loan with a fixed term expiring in the next eighteen months, then schedule a repayment review with each of them well before expiry. The cliff punished brokers who waited for complaints; it rewarded the ones who called first.
