Australia’s Australian Government 5% Deposit Scheme (an expansion of the former Home Guarantee Scheme) is designed to help eligible buyers purchase a home with a 5% deposit (or 2% for eligible single parents/guardians) by providing a government guarantee to lenders and avoiding Lenders Mortgage Insurance (LMI). The scheme was expanded on 1 October 2025 with no income caps and no place limits, alongside higher property price caps. (Treasury)

How it works

Instead of saving a 20% deposit, eligible buyers can borrow up to 95% of a property’s value (or up to 98% in the single-parent stream), with the government guarantee covering part of the lender’s risk. Importantly, the guarantee protects the lender, not the borrower, and does not remove the borrower’s repayment obligations.

Benefits for first home buyers

• Earlier entry: Treasury’s analysis notes that reducing the required deposit can materially shorten the time needed to save (with deposit-saving time having risen materially in recent years). (Office of Impact Analysis)

• Lower upfront costs: avoiding LMI can mean tens of thousands of dollars saved on some loans (depending on price and lender). (Office of Impact Analysis)

• Broader access since October 2025: no income caps and uncapped places (subject to lender assessment and property price caps). (Housing Australia)

Who qualifies (in plain English)

Eligibility is ultimately assessed by participating lenders, but key settings include:

• Australian citizen or permanent resident, at least 18.

• Deposit: at least 5% (first home buyers) or 2% (single-parent/guardian stream). (First Home Buyers)

• Owner-occupier: you must intend to live in the property and generally move in within required timeframes.

• Property must be under the local price cap (caps vary by state/region; e.g., the guide lists $1,000,000 for the ACT).

• Loan structure limits: available for individuals or two joint applicants (not three+).

Housing-market impact, especially under $500k

Because the scheme’s caps (and buyer budgets) tend to cluster activity in the more affordable segments, Treasury has noted that demand effects can concentrate at the lower end of the market. (Office of Impact Analysis)

Since October 2025, debate has sharpened:

• Upward pressure case (concern): The RBA has said it’s hard to quantify precisely, but the expanded scheme is likely to add some upward pressure to housing credit and price growth. Critics argue that boosting purchasing power without enough supply mainly bids up entry-level stock, potentially hurting non-scheme buyers chasing the same homes. (Reserve Bank of Australia)

• Access and stability case (support): Treasury analysis highlights that, historically, the guarantee-backed loan pool has had low arrears and very few payouts to date, suggesting the cohort has not been unusually risky so far—though this could change if conditions deteriorate. (Office of Impact Analysis)

Bottom line for the sub-$500k bracket: the scheme can be a genuine door-opener for deposit-constrained buyers, but it can also increase competition for the same limited entry-level listings—meaning some of the benefit may be capitalised into higher prices rather than lower barriers.
