Every subdivision in Australia ends the same way: a plan is registered and new titles are issued. The person who prepares that plan is a licensed surveyor, and they are usually involved from the first site visit to the day the titles arrive.
This guide explains what a surveyor does at each stage, how their job differs from a town planner's, and how to check that the surveyor you are speaking with is licensed.
Why a subdivision needs a surveyor
A title is only as good as its boundaries. When land is divided, someone has to locate the existing boundaries accurately, decide exactly where the new ones go and record them so the titles office can issue new titles with confidence.
Do I need a surveyor to subdivide? Yes. In every state, the plan that creates new lots has to be prepared by a surveyor who is licensed or registered in that state, and it is lodged with the state's land titles office.
The rules sit in each state's own surveying and land titles laws. Some examples:
- Victoria: plans of subdivision are prepared by licensed surveyors and lodged with Land Services Victoria under the Subdivision Act 1988. The Surveyors Registration Board of Victoria states that only licensed surveyors are legally entitled to perform land and property boundary surveys.
- New South Wales: registered land surveyors are described by the Board of Surveying and Spatial Information as cadastral surveyors, because they maintain the cadastre through the locating and marking of property boundaries.
- Western Australia: land surveyors must be registered with the Land Surveyors Licensing Board under the Licensed Surveyors Act 1909. Surveying land includes re-establishing boundaries that were previously set.
What a surveyor does, stage by stage
The exact steps vary by state and by the size of the job, but most two-lot or small subdivisions follow a similar pattern.
1. Early advice and site information
Before anything is lodged, a surveyor can confirm what is actually on the ground: where the existing boundaries are, where buildings, fences and driveways sit in relation to them, and how the land falls. This matters because a lot that looks large enough on a map can lose usable area to a misplaced fence, an easement or an awkward slope.
Many owners ask a surveyor and a town planner to look at the block together at this stage, so the layout reflects both the planning rules and the measured site.
2. The proposed layout
The surveyor drafts the proposed lot layout that goes with the planning or subdivision application. That drawing shows the new boundaries, lot areas, frontages, any access leg for a rear lot and existing structures that would stay or go.
If a house or shed sits across a proposed boundary, this is where it shows up. The surveyor can test alternatives, for example shifting a boundary to keep a garage on one lot.
3. The application and approval stage
The approval itself comes from the planning authority, which varies by state. In Western Australia, for example, subdivision proposals are first submitted to the Western Australian Planning Commission. In Victoria, a planning permit is required to subdivide land.
During this stage the surveyor may respond to requests for more detail about the layout, levels or easements.
4. Survey and pegging the new lots
Once the subdivision is approved, the surveyor carries out the formal survey. That means locating the existing title boundaries precisely and marking the new boundaries on the ground. The results are what the final plan is built from.
5. The final plan
The surveyor then prepares the plan that will create the new lots. In Victoria it is called a plan of subdivision. In Western Australia freehold lots are created on a deposited plan. The plan records the new boundaries, lot areas and any easements needed for services or access.
6. Lodging and new titles
The surveyor usually lodges the plan with the land titles office. In Western Australia, Landgate notes that the licensed surveyor in charge can lodge the plan before civil works are finished and before final approval, so it can be examined while conditions are being cleared. Approval may be conditional on completing works such as roads, drains and services.
Timing rules apply after approval. In Western Australia, for plans endorsed on or after 9 April 2006, owners have two years from the endorsed date to lodge an application for new titles. After that the plan expires and a fresh subdivision approval is needed.
Surveyor or town planner: who does what
Is a surveyor the same as a town planner? No. A town planner works out whether the planning rules allow the subdivision and prepares the case for approval. A surveyor measures the land, defines the new boundaries and prepares the plan that creates the new titles. Many subdivisions use both.
In practice:
- A town planner reads the zoning, minimum lot sizes, overlays and local policies, and argues the case where a proposal does not fit neatly within the rules.
- A surveyor works with the physical land: boundaries, measurements, levels, easements and the legal plan.
On simple subdivisions, some surveying firms manage the whole application and bring in a planner only where needed. On more complex sites, such as heritage, bushfire or flood-affected land, a planner usually leads and the surveyor supports.
How to check a surveyor is licensed
How do I check that a surveyor is licensed? Each state keeps its own register. In Victoria, the Surveyors Registration Board of Victoria publishes a Register of Licensed Surveyors. In New South Wales, registration is handled by the Board of Surveying and Spatial Information. In Western Australia, it is the Land Surveyors Licensing Board.
A few practical points:
- Check the register for the state where your land is.
- Registration is renewed regularly. In NSW it is renewed annually, so current status is what counts.
- In Victoria, only practising licensed surveyors are authorised to undertake cadastral surveys. Non-practising surveyors are not.
What affects the surveyor's fee
Surveying fees are quoted on scope, so it is worth asking for a written quote that lists what is included. Things that commonly change the price are the number of lots, the size and slope of the land, how easy the existing boundaries are to re-establish, whether easements are needed, and how many rounds of changes the approval process requires.
Government fees for lodging plans and issuing titles are separate and are set by each state's titles office.
Before you call a surveyor
You will get more out of the first conversation if you already know the basics about your block: its zoning, minimum lot size, any overlays such as heritage, bushfire or flood, and roughly where the house and other structures sit.
