Australia's property market has a new class of players competing for entry-level homes. Ever since the federal government dropped the income limits for its flagship first home deposit scheme, wealthy buyers have been rushing through the gates. People earning well over $200,000 are now using taxpayer-backed guarantees to buy properties with tiny deposits, leaving lower-income Australians squeezed out of the very market the policy was designed to help. It is a striking shift in policy direction that has turned a targeted safety net into an open-slather property accelerator.
If you are trying to buy your first home right now, you know the struggle. Saving a 20% deposit in Sydney or Melbourne can take a decade or more. The Australian Government 5% Deposit Scheme, which used to be called the Home Guarantee Scheme, fixes that by letting you buy with just 5% down while the government guarantees the rest to the bank. This bypasses the brutal cost of Lenders Mortgage Insurance. But by opening this shortcut to everyone regardless of how much money they make, the government has injected a fresh wave of high-income demand into an already hot market.
The Policy Shift That Changed the Rules
The old rules were clear. To get a spot in the scheme, an individual couldn't earn more than $125,000 a year, and couples were capped at $200,000. It wasn't perfect, but it kept the focus on middle and lower-income workers who genuinely couldn't bridge the deposit gap.
Then came the massive expansion that took effect late last year. The government removed the income caps entirely. They also uncapped the total number of places available, turning what used to be a competitive annual lottery into an open tap. Property price caps were raised at the same time, meaning you can now use the guarantee on homes worth up to $1.5 million in Sydney and $950,000 in Melbourne.
What happens when you give high-earning couples with massive borrowing power a green light to buy with a tiny down payment? They take it. Wealthy buyers who can easily afford to service a million-dollar loan but just haven't saved up $200,000 in cash are flocking to the program. They are using their high incomes to outbid regular buyers, weaponizing a first home deposit scheme that was meant to be an equalizer.
How High Earners Are Weaponizing the Guarantee
To understand why this is happening, you have to look at how banks view wealthy applicants. A couple earning $250,000 a year can comfortably afford the monthly repayments on a substantial mortgage. Their problem isn't income. Their problem is the sheer time it takes to build up a massive lump sum of cash while paying record-high rents in major capital cities.
Under the new framework, that roadblock disappears. They only need to scrape together $50,000 or $60,000 to get a foot in the door. Because their incomes are so high, banks will eagerly lend them the remaining 95% of the purchase price.
When these buyers enter an auction, they have an immense advantage. A buyer earning $90,000 a year has a strict, unyielding borrowing limit imposed by bank serviceability buffers. A buyer earning double that has room to move. By using the first home deposit scheme, high earners can take all the money they would have spent waiting and saving, and instead use it to outprice the competition right now.
Pouring Fuel on the Suburb Price Fire
Critics and economic analysts have been sounding the alarm on what this actually does to property prices. S&P Global recently warned that the expansion of the scheme could easily backfire by driving up home values at the lower end of the market.
When you give thousands of extra buyers the ability to purchase property immediately, demand skyrockets. If the supply of new houses doesn't match that demand, prices rise. It is basic economics. Treasury's own early modeling suggested the scheme would add to home prices over time, but independent property analysts think the impact will be much sharper, especially for properties sitting just under the regional price caps.
Imagine a modest three-bedroom house in an outer suburb or a booming regional hub like Geelong or Wollongong. A year ago, the bidders for that home were mostly local young families or workers with strict budgets. Today, that same house sees bids from high-income professionals who have shifted their attention down-market to make use of the 5% deposit shortcut. The result is a floor under property prices that keeps pushing the entry point out of reach for average earners.
The True Financial Risk of a Five Percent Deposit
There is a huge misconception that getting a government guarantee makes your mortgage safer or smaller. It doesn't. This is the biggest trap of the first home deposit scheme, and it is something many eager buyers ignore until it is too late.
The government does not give you any money. They do not pay off a cent of your loan. They simply act as a guarantor for the 15% gap so the bank doesn't force you to buy insurance. You are still borrowing 95% of the property value. That means your starting debt is enormous, and your monthly repayments will be significantly higher than if you had saved a traditional 20% deposit.
Consider the reality of buying a $800,000 property:
With a traditional 20% deposit, you save $160,000 and borrow $640,000. Your monthly repayments are based on that smaller debt.
With the first home deposit scheme, you put down $40,000 and borrow a massive $760,000.
You are paying interest on an extra $120,000 from day one. In an environment where interest rates stay higher for longer, that extra debt burden translates into thousands of dollars in extra interest payments every single year. High earners can handle that extra strain because their paychecks are large enough to absorb the hit. For an average family, it leaves absolutely zero margin for error if someone loses a job or faces an unexpected medical bill.
What You Should Do If You Are Navigating This Market
If you are an average earner trying to compete against wealthy buyers using this program, you have to change your strategy. Waiting around and hoping for prices to fall is rarely a winning move in Australian real estate. Instead, you need to maximize every tool available while protecting your financial downside.
Get Pre-Approved Before You Even Look at a House
Do not wait until you find a property to talk to a broker. Participating lenders have strict internal caps on how many low-deposit loans they will hold on their books, even with the government guarantee. Get your documents sorted, get your eligibility verified, and lock in a 90-day pre-approval spot through an authorized bank.
Look at the Fine Print on Alternative Programs
If the main scheme is too crowded, look at more targeted options that still have income limits. The federal government Help to Buy scheme, which involves shared equity, still keeps strict income caps of $100,000 for individuals and $160,000 for joint applicants. Because high earners are banned from this program, you won't be competing against people making a quarter of a million dollars a year.
Run Your Numbers Against a Three Percent Buffer
Banks will test your ability to pay your mortgage at a rate 3% higher than what they are offering you. Do the same thing yourself. If you are borrowing 95% of a property's value under the first home deposit scheme, sit down with a calculator and make sure you can still afford the grocery bills if interest rates tick upward.
Focus on Capital Growth Suburbs Under the Price Cap
If you buy at the absolute limit of the local price cap, you risk overpaying in a localized bubble. Target suburbs where the median price sits comfortably below the government cap. This gives you room to negotiate without feeling forced to max out your borrowing capacity just to beat out a high-income rival.
The rules of the game have shifted, and the entry-level property market is more competitive than ever. High earners have recognized that they can use the system to bypass years of saving. To survive in this market, you need to understand exactly what you are up against, act with speed, and never take on a debt load that leaves your personal budget on the brink of collapse.
