    Subdivision

    Split one block into two or more lots and sell the land value separately

    What is Subdivision?

    Subdivision involves splitting a single block of land into two or more separate titled lots. Each new lot can be sold independently or built on. In established suburbs with large blocks, the sum of the two new lots is often significantly greater than the value of the original property.

    How it works

    1. 1Engage a town planner to assess whether the site can be subdivided (zoning, lot size, frontage)
    2. 2Lodge a Development Application (DA) with council for subdivision approval
    3. 3Upon approval: engage a surveyor to create a plan of subdivision
    4. 4Apply to Land Registry for new titles
    5. 5Sell the new lot(s) vacant, or build on them first then sell

    Worked example

    You buy a 900sqm block in a suburb with a 450sqm minimum lot size.
Purchase price: $950,000. Subdivision costs: $80,000 (DA, surveyor, council, legal).
After subdivision: two 450sqm lots, valued at $850,000 (with the house) and $650,000 (vacant).
Total value: $1,500,000. Gain before tax, GST, holding and selling costs: $1,500,000 – $950,000 – $80,000 = $470,000.
Timeline: often 18–24 months from DA lodgement to settling the new lot.

    Pros

    • Can release a lot of equity from a single property without building anything
    • Subdivided lots can be sold immediately or developed for additional profit
    • Growing demand for smaller lots in established suburbs

    Cons

    • DA process is slow (6–18 months) and uncertain, council may refuse
    • Significant upfront costs: town planner, DA fees, surveyor, council contributions
    • Neighbours, heritage, and flood/bushfire overlays can block approval

    Risks

    • Council may impose conditions that make the project unviable
    • GST may apply if you are in the business of property development (seek tax advice)
    • If the subdivision is treated as a profit-making scheme, full ordinary income tax may apply (not just CGT)

    Tax treatment

    If one-off: capital gain realised on sale of new lot, 50% CGT discount if 12+ months. If regular activity or business: profit assessable as ordinary income, not CGT. GST: if you are "carrying on an enterprise" of subdivision, GST applies and you must register for ABN/GST. Always seek specialist advice before embarking on subdivision.
