About Australian Home Loans

The Australian home loan market is dominated by variable-rate products with optional 1–5 year fixed periods. Most loans are full principal-and-interest with 25 or 30-year terms, and offset accounts and redraw facilities are standard features that let borrowers reduce interest while maintaining access to surplus funds. Lenders are required by ASIC to disclose a comparison rate alongside the headline rate, capturing most fees in a single number.

Serviceability is governed by APRA, which requires lenders to assess borrowers at the contract rate plus a 3% buffer. The Household Expenditure Measure (HEM) provides a floor on assumed living costs. Loans above 80% LVR generally require Lenders Mortgage Insurance (LMI), a one-off premium that protects the lender — not the borrower — and is typically capitalised onto the loan balance.

Stamp duty is the largest one-off cost on a purchase and is set by each state and territory, with significant variation. First home buyers may qualify for full exemption or major concessions in most states, and the federal Home Guarantee Scheme allows eligible buyers to purchase with a 5% deposit and no LMI. The First Home Super Saver scheme (FHSS) lets buyers save toward a deposit through their superannuation at concessional tax rates.
