Australia Mortgage Lending Market 2026: Policy Reform, Digital Lending & Refinancing Surge

The Australia mortgage lending market is expanding steadily as home buyers, property investors, refinancers and financial institutions navigate a complex landscape of evolving policy settings, competitive lender dynamics and digital transformation. Mortgage lending — encompassing conventional loans, fixed and variable rate products, and refinancing — serves as the financial backbone of Australia's residential property sector, facilitating access to housing for owner-occupiers, first home buyers and investors. According to IMARC Group, the market size reached USD 32,525.03 Million in 2025 and is projected to reach USD 47,081.16 Million by 2034, exhibiting a compound annual growth rate (CAGR) of 4.20% during 2026–2034. As the broader Mortgages in Australia market industry is valued at $155.1 billion in 2026 (IBISWorld), the sector remains a cornerstone of the domestic financial economy.

What's Driving Market Growth?

Expanded Government Homeownership Schemes. The Home Guarantee Scheme has been a material driver of lending activity. From October 2025, the scheme has allowed all first-home buyers to purchase with a 5% deposit without paying lenders mortgage insurance, materially lowering entry barriers and broadening the addressable borrower base. This has intensified competition at the more affordable end of the market, with more young people seizing the opportunity to break the rent cycle and lock in their first home sooner.

Resilient Investor Demand Outpacing Owner-Occupiers. Investor lending is forecast to outpace owner-occupier activity in 2026 despite rate pressures and tax uncertainty. Money.com.au forecasts total home lending to grow around 7% in 2026 to 594,279 loans, with investor loans tipped to rise 13% to roughly 246,600, while owner-occupier growth is expected to slow to about 3%. In New South Wales, investor lending is projected to climb 16% to 77,470 loans, while Victoria continues to close the gap, with investor lending up 21% over the past year.

Refinancing Surge Amid Rising Rates. Borrowers are responding to successive rate rises by seeking more competitive products. The value of refinancing submissions processed through broker networks increased 18.7% year on year in the March 2026 quarter, with Victoria and Tasmania recording a year on year increase of more than 28% in refinance submissions. Refinancing accounted for 34% of total mortgage demand in February 2026, and more than 640,000 home loans were renegotiated or switched in 2025.

AI Driven Lending Transformation. Australian lenders are rapidly embracing digital mortgage solutions to enhance customer experience and operational efficiency. The federal government is also recruiting AI to speed up housing approvals, with a $105.9 million commitment over four years to develop an AI tool that guides proponents and shares environmental data to get more projects approved. Meanwhile, APRA's new rules from February 2026 cap high debt to income loans (six or above) at 20% of new lending.

What the Opportunities Are?

Refinancing Solutions and Retention Strategies. With refinancing accounting for a significant portion of mortgage demand, lenders that offer competitive refinancing packages, streamlined switching processes and attractive retention offers capture valuable market share. The trend of refinance upgrades with the same lender up 15.2% year on year suggests that institutions investing in customer retention programmes can secure loyalty in a volatile rate environment.

Digital End to End Mortgage Platforms. Key players are driving the market by expanding digital platforms, diversifying product portfolios and strengthening broker partnerships to enhance customer acquisition and improve lending efficiency. Australian lenders that invest in fully digital origination, automated credit assessment and real time approval workflows will gain operational advantages and improved customer satisfaction.

First Home Buyer and Affordable Housing Finance. With expanded government schemes lowering deposit barriers, products tailored specifically to first home buyer constraints — including lower deposit requirements, flexible servicing tests and targeted rate discounts — present significant growth opportunities. The Federal Budget's $2 billion over four years for critical enabling infrastructure, supporting up to 65,000 new homes, complements this segment.

Specialised Investor Products and Portfolio Lending. As investor demand continues to outpace owner occupier growth, lenders that develop sophisticated investor focused products — including interest only options, portfolio lending facilities and tax aware structuring — will capture the growing investor segment. However, the one year reprieve on negative gearing and CGT reforms set for the Federal Budget introduces near term uncertainty that specialised products can help navigate.

Mutual and Non Bank Lender Expansion. The mutual bank and credit union sector has more than tripled its combined mortgage book in seven years, amassing 150.9billioninresidentiallending∗∗andnearlydoublingitsmarketsharefrom3.2150.9billioninresidentiallending∗∗andnearlydoublingitsmarketsharefrom3.227.3 billion in new mortgage balances — growth of 22% in a single year, compared to 6.9% for the market as a whole.
