DHOAS, HPAS, and the First Home Guarantee: How ADF Members Can Stack These Benefits

When I was still serving, I knew DHOAS existed. I had heard of HPAS. I was vaguely aware there were schemes designed to make home ownership more accessible for defence members.

What nobody explained to me was how they actually worked, how they interacted with each other, which lenders you had to use, and what I was leaving on the table by not understanding the detail.

That gap in knowledge is not unusual. It is the norm. Most ADF members know these schemes exist in the same way they know about fringe benefits tax: in theory, without the detail that actually matters when you are trying to use them.

This post is the detailed version.

The Three Schemes and What They Each Do

There are three primary tools available to ADF members buying a home. Each does something different, and they can be used together.

HPAS (Home Purchase Assistance Scheme) is a one-time cash payment made to eligible ADF members to help with the costs of purchasing a home. It is not a loan and it does not need to be repaid. The amount varies based on rank and location, and it is designed to offset some of the transaction costs that come with buying, including stamp duty, legal fees, and agent charges.

HPAS is means-tested and requires you to have a certain period of service completed. It is taxable income in the year you receive it, which is something many members are not told upfront.

DHOAS (Defence Home Ownership Assistance Scheme) is not a grant. It is an ongoing interest subsidy paid directly to your lender on your behalf. The payment reduces the interest charged on your home loan every month. The subsidy amount tiers up based on your accumulated eligible service days: the longer you serve, the larger the monthly subsidy.

This distinction matters enormously. Because DHOAS reduces interest, it works most powerfully when combined with a loan product that also has an offset account. More on that below.

The First Home Guarantee (FHBG) allows eligible first home buyers to purchase with a 5% deposit without paying Lenders Mortgage Insurance. The federal government guarantees the remaining deposit gap up to 15%, so the lender is covered without the cost falling on you.

Following the 2026-27 budget, income caps on the First Home Guarantee have been removed and places are now unlimited. Any eligible first home buyer can access it.

Why Most ADF Members Do Not Maximise DHOAS

DHOAS is the scheme where I see the most value left on the table, for one reason above all others: approved lenders.

DHOAS is only available through lenders who are specifically approved to participate in the scheme. Not every bank offers it. Not every credit union. Certainly not every lender across the 35+ we access. A meaningful portion of the lending market does not participate.

Here is where the problem compounds: most general mortgage brokers do not know which lenders are approved for DHOAS and which are not. So when an ADF member walks into a broker or bank who does not specialise in defence lending, they often end up on a loan product with a lender who cannot support DHOAS at all. The subsidy then goes unclaimed, or the member has to refinance later to access it, at cost.

The second issue: DHOAS is an interest subsidy, not a principal reduction. The subsidy comes in as a credit against your interest charges each month. This means it is most powerful when your loan balance is highest, which is early in the loan life. Members who wait years before understanding and claiming DHOAS have lost subsidy they can never recover.

The Offset Account Interaction

Here is the detail that almost nobody explains.

DHOAS reduces your interest liability. An offset account also reduces your interest liability by offsetting your loan balance with savings you hold in the linked account. When you combine both, every dollar sitting in your offset account is reducing the interest base that DHOAS then applies its subsidy to.

In practical terms: DHOAS provides a percentage-based reduction on your interest. The offset account reduces the principal on which that interest is calculated. Together, they compress your effective interest cost significantly more than either tool does in isolation.

This means the DHOAS-approved lender you choose needs to offer a genuine, functional offset account, not all of them do to the same quality, and the loan product needs to be structured to allow the offset to work effectively. Getting this wrong is common. Getting it right requires knowing which lenders offer the combination.

Can You Stack All Three at Once?

Yes. An eligible ADF first home buyer can, in the right circumstances, receive HPAS toward purchase costs, access the First Home Guarantee to buy with a 5% deposit and avoid LMI, and use DHOAS to reduce ongoing interest charges.

That combination represents a significant financial advantage over what most Australians have access to when buying their first home. It is one of the most underutilised packages in the lending market.

The structure requires careful sequencing. HPAS is applied at purchase and declared as income. The First Home Guarantee requires a specific application process through the approved lender. DHOAS requires the loan to be with an approved lender and the subsidy to be formally registered. All three need to be set up correctly from the start.

Trying to layer them on after the fact is harder, more expensive, and sometimes not possible without a full refinance.

One Important Limitation: DHOAS Cannot Be Used on Construction Loans

This is the detail that catches the most people off guard, particularly ADF members who are drawn to building new rather than buying established.

DHOAS applies to a completed property with a standard mortgage. It cannot be used during the construction phase of a build. If you take out a construction loan to build a home, DHOAS is not available until construction is complete and the loan converts to a standard home loan at final drawdown.

The practical implication: during the construction period, you are paying interest on drawdown amounts without the DHOAS subsidy reducing that cost. For a build that takes 12 to 18 months, that is 12 to 18 months of interest without the subsidy running. On a large construction loan, that gap adds up.

This does not mean ADF members should avoid building. There are other compelling reasons to consider new construction, including the First Home Guarantee applying to new builds, the permanent retention of negative gearing on new properties for investors, and the obvious benefit of a brand-new home built to your specifications. But if your primary motivation for building is to access DHOAS benefits sooner, you need to know the subsidy will not start until settlement of the completed build.

For ADF members weighing up building versus buying established, the DHOAS timing difference is a real financial variable worth modelling before you commit to either path.

What Happens to DHOAS When You Are Posted

This is one of the most frequently asked questions and one where the answer surprises many members.

DHOAS is attached to the loan, not the location. If you are posted interstate and rent out your DHOAS property, the subsidy continues. However, there are conditions around owner-occupation intent and the duration of the rental period. Renting out a DHOAS property while posted is generally permitted and understood as part of the ADF lifestyle, but it requires notifying DVA and there are limits on how long you can rent it out before the status is reviewed.

The practical read: DHOAS is designed with the posting cycle in mind. Defence Housing Australia and the Department of Veterans Affairs understand that ADF members do not always live in their own properties. But you need to be across the rules and communicate appropriately, rather than assuming the subsidy just keeps running silently in the background regardless of what you do with the property.

The Rank and Service Tier Structure

DHOAS subsidies are not flat. They increase based on your tier of accumulated eligible service days.

Members with fewer service days sit on the lower tiers and receive a smaller monthly subsidy. Members with longer service history sit on higher tiers with more significant subsidies. The progression is meaningful: a member on a higher tier receives considerably more subsidy each month than someone just commencing DHOAS eligibility.

This creates an important consideration for long-serving members who have not yet claimed DHOAS. Every month you have been eligible but not enrolled is a month of subsidy you have not accessed. The subsidy does not backdate. It starts from enrolment.

If you are a senior NCO or officer who has served for many years and has not yet set up DHOAS, the first step is understanding which tier you sit on and what the monthly subsidy at that tier is worth over the remaining life of your loan.

What ADF Members Should Do Right Now

The starting point is a clear assessment of what you are eligible for and what you are currently accessing.

If you are not yet a homeowner: understand which schemes apply to your situation based on your service length, rank, and whether you are a first home buyer. Model what the combination of HPAS, DHOAS, and the First Home Guarantee does to your effective purchase cost and ongoing repayments before you commit to any lender.

If you are an existing homeowner with DHOAS: check that your loan is with an approved lender, that your offset account is set up and functioning correctly against your home loan balance, and that your tier reflects your current service days. DHOAS tiers can be reviewed and updated as your service accumulates.

If you are an existing homeowner without DHOAS: understand why not. Is it that you are not yet eligible? Or is it that nobody set it up correctly when you bought, or that you ended up with a non-approved lender? If the latter, the question is whether refinancing to an approved lender to access DHOAS stacks up financially given your current balance and remaining loan term.

We work with ADF members regularly and we are across the full picture of how these schemes interact. The conversation is more specific than a standard borrowing assessment, but it is one we have done many times.

If you are in the ADF and you are not certain you are maximising every entitlement available to you, that uncertainty is worth resolving. There are real dollars sitting in these schemes for members who know how to access them.
