ISCOVER
The big four banks have maintained steady growth, while Macquarie Bank continues to rank among the fastest-growing mortgage lenders in Australia.
Mortgage lending for owner-occupied and investment homes by the big four grew 0.65 per cent over June to $1.73 trillion, a rise of $11.2 billion over the month, according to the Australian Prudential Regulation Authority (APRA).
All four majors posted positive month-on-month growth across owner-occupied and investment home lending in June.
The latest release of the Monthly Authorised Deposit-taking Institution Statistics (MADIS) showed the Commonwealth Bank of Australia (CBA) remains the largest lender, with a total mortgage book of $593.66 billion, up 0.8 per cent month over month, the highest among the majors.
Australia and New Zealand Bank (ANZ) had the smallest year-on-year increase among the majors for its mortgage book, growing 0.49 per cent to $317.71 billion over the month.
Mortgage lending at National Australia Bank (NAB) rose 0.76 per cent to $334.67 billion, the third-largest total of the big four banks.
Meanwhile, Westpac’s loan book increased to $487.94 billion at the end of June, including $323.48 billion in owner-occupier lending and $164.46 billion in investor loans.
Its total mortgage book grew 0.51 per cent over the month.
Macquarie remains best of the rest
While the big four banks continue to dominate in total volume, the non-major banks are seeing the fastest rates of growth.
Macquarie Bank remains one of the fastest-growing mortgage lenders in the country. It increased its total book to $144.53 billion in June 2025 – up 2.31 per cent month on month – one of the highest growth rates across all banks and lenders.
Almost two-thirds of Macquarie’s loans at the end of June comprised owner-occupied.
According to the 2025 Third-Party Lending Report, carried out between 17 February and 30 April 2025, Macquarie Bank overtook the majors as the most commonly used lender in the third-party channel for the first time.
Two-thirds (66 per cent) of brokers used Macquarie Bank in the 12 months to April, surpassing ANZ (64 per cent), CBA and Westpac (both 58 per cent), and NAB (56 per cent).
