Australian mortgage holders grappling with the highest interest rates in 18 years could save more than $3,000 annually through a simple review of their home loans, according to industry experts.

The Reserve Bank of Australia raised the cash rate to 4.85 per cent following its fifth hike of the year, pushing rates to levels not seen since 2008. Major lenders including Westpac, NAB, Commonwealth Bank, ANZ, and Macquarie confirmed they would pass the full increase on to variable home loan customers by mid-November.

Veterans in the lending sector report that stressed borrowers are focusing heavily on central bank decisions while overlooking practical steps they can control. Mortgage broker and The Mortgage Coach co-founder John Maxwell noted that homeowners frequently rely solely on their existing lender, missing out on more competitive terms available elsewhere.

According to broker calculations, trimming just half a percentage point off an $800,000 mortgage at a 7 per cent interest rate over 30 years can save approximately $266 each month, exceeding $3,000 across a year and approaching $96,000 over the lifetime of the loan.

Experts emphasize that borrower loyalty rarely yields the best financial outcomes, as lenders frequently reserve competitive rates for new customers rather than existing ones. With more than 100 home lenders operating across Australia, homeowners are advised to seek independent reviews from mortgage brokers to explore alternative loan structures, features, and fees.
