House and Land Packages South Australia: What to Know Before You Sign

House and land packages dominate the SA first home buyer market right now, and there's a clear reason: they're the only way to access both the $15,000 FHOG and zero stamp duty simultaneously. But the financial incentives have pushed large numbers of buyers into contracts they don't fully understand, and the gap between the advertised package price and the total cost of construction is often substantial.

Here's what's actually involved, where the value exists, and what to check before you sign anything.

Why New Builds Are Dominant in SA

South Australia's policy settings create a stark financial divide between new and established homes. For eligible first home buyers:

• New builds: zero stamp duty + $15,000 FHOG cash payment
• Established homes: full stamp duty (up to 5.5% of purchase price) + no FHOG

On a $600,000 purchase, that difference amounts to over $40,000 in real cash. First home buyers rationally respond by gravitating toward new construction, which is exactly what the policy intends — it's designed to stimulate housing supply.

The result is that house and land packages have become the dominant entry point for first home buyers in SA, particularly in the northern growth corridors.

How House and Land Packages Work in SA

A house and land package is typically structured as two separate contracts:

1. Land contract: You purchase the land component from the developer. Settlement usually occurs relatively quickly, at which point you own the block and start making land loan repayments.

2. Building contract: Separately, you sign a contract with a volume builder to construct the home on your land. Construction drawdowns are released in stages as work progresses — typically at slab, frame, lock-up, fixing, and practical completion.

The two-contract structure has a practical implication for stamp duty: you pay stamp duty on the land value only (if applicable), not on the total completed value of the home. For eligible first home buyers, the stamp duty exemption covers the land purchase, so both contracts attract zero duty.

Some packages are structured as a single "turnkey" contract where the developer handles both the land sale and construction. These can simplify the finance arrangement but require careful scrutiny of what's actually included in the turnkey price.

Where Packages Are Available

Northern Suburbs

The northern suburbs — specifically the City of Playford — are where the bulk of SA's new build activity for first home buyers is concentrated. Key development areas include:

Playford Alive (Andrews Farm, Munno Para West, Angle Vale, Eyre): The largest government-backed land release program in SA. Renewal SA has developed thousands of allotments here, with approximately 30% capped at under $260,000 under HomeSeeker SA's affordable housing mandate. The City of Playford recorded median house prices around $720,000 in late 2025, with annual growth exceeding 17%.

Edinburgh Parks / RAAF Base precinct: New residential and mixed-use development is occurring around these northern logistics and defence hubs, creating emerging corridors for affordable new builds.

Concordia: Located further north near Gawler, Concordia is one of SA's largest greenfield rezoning projects. It's further from central Adelaide but offers some of the most affordable allotment prices in greater metropolitan SA.

House and land packages in the northern suburbs typically start around $450,000–$550,000 for a 3-bedroom, 2-bathroom home on a 200–350sqm allotment, depending on the builder, inclusions, and lot position.

Southern Suburbs

Aldinga: A sustainability-focused development in Adelaide's south, with 25% of properties mandated as affordable housing. HomeSeeker SA listings appear regularly here. The development includes net-zero building standards, which can add to upfront build costs but reduces ongoing energy bills.

Morphettville and surrounds: Closer to the city, new townhouse and unit developments appear periodically, often as part of infill projects. Allotment sizes are smaller, and prices trend higher than the northern corridors.

Adelaide Hills / Mount Barker

Mount Barker has become Adelaide's largest growth satellite. It's attracting significant infrastructure investment and offers land prices lower than comparable northern corridors, with the appeal of a country town environment 35 minutes from the city.

However: bushfire risk is a critical due diligence issue here. Homes in the Adelaide Hills require a Bushfire Attack Level (BAL) assessment. Depending on the site, compliance costs can add $5,000–$50,000 or more to your build contract. Many buyers sign a base-price house and land package in the Hills without factoring in BAL requirements, then find themselves unable to finance the mandated upgrades. Check the BAL rating before you commit to land in the Hills.

The Hidden Costs of House and Land Packages

The advertised "house and land package price" is almost never the final cost. Common additional expenses:

Site costs: If your block isn't perfectly flat (most aren't), cut and fill or retaining walls add cost. In the northern suburbs where clay soils are reactive, site preparation and engineered slab requirements can add $10,000–$30,000 to a standard contract.

Upgrades and inclusions: Display homes are staged with premium tiles, stone benchtops, and upgraded appliances. The base package typically includes builder's standard — which is meaningfully different from what you see in the display. Buyers frequently spend $15,000–$30,000 in upgrades to get close to the display standard.

Landscaping and fencing: Almost never included in the house contract. Budget $10,000–$20,000 for a basic lawn, driveway, and boundary fencing.

Driveway and letterbox: Often excluded from turnkey packages despite appearing in artist impressions.

Connection fees: SA Water and ElectraNet connection fees are site-specific and sometimes excluded from the package price.

Driveways to masterplanned estates: Some new estates in the northern corridors require developer-mandated façade and landscaping standards (enforced by Community Title by-laws). If your chosen design doesn't comply, you'll need to upgrade.

A genuine total cost estimate for a northern suburbs house and land package priced at $480,000 might realistically land at $530,000–$560,000 by the time you've added site costs, upgrades, landscaping, and connection fees. Factor this into your borrowing capacity assessment before you sign.

Choosing a Builder

The SA construction sector has faced significant headwinds since the pandemic. Material shortages — particularly PVC pipes required for slab drainage — caused widespread delays, and several volume builders collapsed in 2022–2024. Buyers with contracts under those builders faced months of uncertainty, stalled builds, and in some cases, material shortfalls that weren't covered by their original fixed-price contracts.

When evaluating a builder:

• Check their QBCC (or SA equivalent — Consumer and Business Services SA) licence status
• Ask specifically about their current build pipeline and typical handover timeframes
• Ask whether their base contract is genuinely fixed-price or cost-plus
• Request references from buyers who completed builds in the last 12 months
• Understand what happens to your contract if the builder enters administration

Fixed-price contracts provide the most protection in an inflationary environment. Cost-plus arrangements shift material price risk onto you — which can be significant when quarry product and PVC pipe costs are volatile.

Grant Compliance and Construction Timelines

If you're claiming the FHOG and zero stamp duty through a building contract, you must:

1. Commence construction within the timeframe specified in your contract (typically within six months of land settlement)
2. Complete construction and receive practical completion
3. Move into the home as your principal place of residence within 12 months of practical completion and live there continuously for at least six months

Delays caused by the builder can create compliance risk if RevenueSA doesn't grant an extension. Document all builder communications meticulously. RevenueSA has discretion to extend deadlines when delays are demonstrably outside the buyer's control — but you need a paper trail.
