First home buyers in South Australia: every grant, concession and scheme

Stamp duty for first home buyers

Eligible first home buyers pay no stamp duty on a new home, an off the plan apartment or vacant land to build on, at any value, for contracts signed from 13 February 2025.

There is no first home buyer relief for an established home in South Australia, so a first home buyer buying an existing house pays full duty. That makes the choice between new and established unusually expensive here.

For the full rate tables and how stamp duty is worked out, see stamp duty in South Australia.

The First Home Owner Grant

The South Australian First Home Owner Grant pays up to $15,000 toward a new home, with no property value cap for contracts from 6 June 2024. The grant is paid for new homes only, so an established home doesn't qualify. You generally need to live in the home as your principal place of residence for a set period.

National schemes you can use in South Australia

These come from the Australian Government and work alongside South Australia's duty relief and grant. In South Australia the 5% Deposit Scheme price cap is $900,000 in Adelaide and regional centres, $500,000 elsewhere, and the Help to Buy cap is $900,000 in Adelaide and regional centres, $500,000 elsewhere.

The 5% Deposit Scheme

The Australian Government 5% Deposit Scheme (formerly the Home Guarantee Scheme) lets first home buyers buy with a deposit of 5%, and single parents or legal guardians with 2%, without paying lenders mortgage insurance. The government guarantees part of the loan, which is what lets the lender skip the insurance. Since 1 October 2025 there are no income caps and no waitlist; the limits are property price caps that vary by state and area.

Help to Buy

Help to Buy is shared equity: you put in at least 2%, borrow from a participating lender, and the government contributes up to 30% of the price of an existing home or up to 40% of a new one, in exchange for that share of the home's value. You can buy the share back over time or repay it when you sell. Applicants must be Australian citizens with taxable income at or below $103,000 (single) or $165,000 (joint applicants and single parents), and the home has its own price caps.

The First Home Super Saver scheme

Through the First Home Super Saver scheme you can make voluntary contributions to super and later withdraw them, with associated earnings, for a first home deposit: up to $15,000 of contributions from any one financial year and $50,000 in total. Because concessional contributions are taxed at 15% inside super rather than at your marginal rate, it can grow a deposit faster for many earners. Ask the ATO or a tax adviser how it applies to you.

What it takes in cash: a worked example

Say you are buying an established home in Adelaide for $900,000 with the 5% Deposit Scheme. The cash you need at settlement is roughly:

The loan is the harder part: a lender has to be satisfied you can repay it at today's rates plus a 3 percentage point buffer, after living costs and any debts. That is what the Borrowable check works out for you.

Before you start looking

• Know your number first. Your borrowing capacity, plus your deposit, less stamp duty and costs, is the price range that actually works. Agents' price guides won't tell you that.
• Credit card limits count, even if you pay them off. Lenders assume the full limit is in use. Reducing or closing a card you don't need can add tens of thousands to what you could borrow. See why your credit card limit matters.
• HECS reduces borrowing power because the compulsory repayment comes out of your take home pay. See how HECS affects a home loan.
• Get your finance lined up before you make an offer, especially at auction, where a winning bid is unconditional.
