Of all the development application categories we track, subdivision is the biggest. As of February 2026, it accounts for 672 DAs out of 17,929 total applications in our database (3.7%), more than renovations, new dwellings, or any other single category.

That number represents the front end of Australia's housing pipeline. Every subdivision DA is land being cut up into smaller lots, and each of those lots will eventually need a house, a driveway, a fence, and a connection to services. For tradies, this is where the work starts.

Why Subdivision Leads Every Category

Category DAs Share
Subdivision 672 3.7%
Renovation / Extension 577 3.2%
New Dwelling 449 2.5%
Tree Removal 208 1.2%
Commercial / Industrial 156 0.9%
Multi-Dwelling / Townhouse 121 0.7%

Subdivision being the top category makes sense when you look at where Australia's development is concentrated. The busiest suburbs in the country (Cornubia with 199 DAs, Greenbank with 128, Yarrabilba with 121) are all greenfield areas where large parcels are being divided into residential lots.

This is the classic Australian growth model: farmland and semi-rural lots get rezoned, subdivided, serviced, and sold to builders. The subdivision DA is the first domino.

Where Subdivisions Are Concentrated

Subdivision activity clusters in the growth corridors that dominate our overall DA rankings.

Region Key suburbs Driver
SE Queensland (Logan) Cornubia, Greenbank, Yarrabilba, Bahrs Scrub Master-planned communities, active land release
SW Sydney Austral, Leppington, Menangle Park Aerotropolis, 17,000+ homes planned
Melbourne corridors Casey, Cardinia, Wyndham, Melton Population growth pushing outward
Adelaide fringe Onkaparinga and surrounds Steady infill and fringe expansion

South East Queensland is the epicentre. The Logan corridor is generating subdivision DAs at a pace that no other region in Australia matches. Master-planned communities like Yarrabilba are still in active land release phases with Stage 10 and 11 registering lots through 2026, meaning the subdivision pipeline has years of runway left.

South-Western Sydney is the second hotspot. The Western Sydney Aerotropolis precinct is accelerating land releases, and councils like Camden and Campbelltown are processing subdivision applications alongside the resulting new dwelling DAs.

Melbourne's growth corridors (particularly Casey, Cardinia, Wyndham, and Melton) contribute VIC's share. Activity remains strong as Melbourne's population continues to push outward.

South Australia also contributes, with Onkaparinga and other Adelaide fringe councils processing a steady stream of subdivision applications.

The Trades That Benefit First

Subdivision isn't just one job. It's a chain. Here's how the work flows.

Trade When they enter What they do
Civil contractors First on site Earthmoving, roads, drainage, stormwater
Surveyors Day one Plan of subdivision, certification
Fencing Mid-construction + post-sale Temporary hoarding, then permanent boundary fences
Service providers During civil works Plumbing, electrical, gas connections to each lot
Landscapers Tail end Driveways, paths, retaining walls, gardens

Civil contractors are first on site. Always. Earthmoving, road construction, drainage, and stormwater infrastructure all have to be completed before a single house lot is ready for sale, which means civil contractors who track subdivision DAs have months of advance notice before their competitors even know a project exists.

Fencing contractors pick up work at two stages: temporary fencing during construction, then permanent fencing once lots are sold and houses go up. In a suburb like Yarrabilba with 121 DAs, that could translate to hundreds of individual fencing jobs over the following 12 to 18 months. Not a bad pipeline from one data point.

From DA to Contracts: The Timeline

A subdivision DA lodged today doesn't mean work starts tomorrow. Here's the typical sequence:

Stage Duration Who's working
DA assessment 2–6 months Surveyors, planners
Civil works 6–12 months Civil contractors, earthmovers
Lot registration 2–4 months Surveyors, conveyancers
House construction 12–18 months per lot Builders, then all finishing trades

For tradies, a subdivision DA is a 6 to 18 month forward indicator. That's valuable planning time. Knowing which suburbs are lodging subdivision DAs now tells you where the house construction and finishing trades work will be in a year.

What to Watch For

Not all subdivisions are equal. A 2-lot subdivision of a suburban backyard is very different from a 200-lot estate.

Lot count matters. Large subdivisions in growth areas generate the most downstream work. Look for applications in master-planned communities and greenfield release areas.

Sequential stages. Big estates subdivide in stages. If you see Stage 3 being lodged, Stages 1 and 2 are already under construction, which means there are builders on site right now who need subcontractors, and Stage 4 is probably being designed, giving you a forward pipeline that extends well beyond the immediate opportunity sitting in front of you. Start quoting.

Council activity trends. A council that's processing a lot of subdivision DAs now will be processing a lot of new dwelling DAs in 12 months. Track both categories to build your pipeline.

Key takeaway: A subdivision DA is a 6 to 18 month forward indicator for house construction and finishing trades. Knowing which suburbs are lodging subdivision DAs now tells you where the work will be in a year.
