When it comes to property, construction, or development, accuracy is everything. That’s where land surveyors come in. But what exactly does a land surveyor do—and why might you need one? In this blog, we break down the essential role of land surveyors, the types of surveys they perform, and when you should consider hiring one.
Understanding the Role of a Land Surveyor
A land surveyor is a licensed professional who measures, maps, and records the dimensions of land and its features. Their work forms the foundation for a wide range of property-related activities—from establishing boundary lines to assisting in large-scale developments.
Using advanced technology and precise calculations, surveyors provide data that supports planning, legal documentation, building works, and land subdivision. Their measurements are legally recognised and often required for council approvals and property transactions.
Key Responsibilities of a Land Surveyor
Here are some of the core tasks a land surveyor performs:
1. Boundary Identification
One of the most common reasons people hire a land surveyor is to identify exact property boundaries. This is crucial when:
- Buying or selling land
- Fencing a property
- Resolving boundary disputes
- Undertaking renovations or extensions
2. Topographic Surveys
Surveyors map the natural and man-made features of a property, including trees, slopes, buildings, and utilities. These detailed maps are used in planning and design for construction or landscaping projects.
3. Construction Set-Outs
Before builders can begin construction, surveyors provide set-out marks to guide the placement of structures. This ensures the build aligns with approved plans and doesn’t encroach on neighbouring properties.

4. Subdivision and Land Development
When landowners want to divide a large block into smaller lots, a surveyor manages the subdivision process. This includes:
- Preparing subdivision plans
- Ensuring compliance with zoning laws
- Lodging documentation with the relevant authorities
5. Strata and Title Surveys
For multi-dwelling buildings or unit developments, surveyors produce plans that define ownership boundaries, common areas, and access routes, enabling registration of strata titles.
6. Monitoring and Compliance Surveys
In infrastructure projects, surveyors monitor changes over time—such as land movement, settlement, or construction progress—to ensure ongoing compliance and safety.
Tools of the Trade
Modern surveyors use sophisticated tools and technology to perform their work with accuracy and efficiency, including:
- GPS and GNSS receivers
- Total stations
- 3D laser scanners
- Aerial drones
- CAD and GIS software
When Should You Hire a Land Surveyor?
You should consider hiring a land surveyor when:
- You’re purchasing land and want to confirm boundaries
- You’re building near property lines
- You’re subdividing land or developing a block
- You’re applying for a DA (Development Application)
- There’s a legal or neighbour dispute over boundaries
Their services provide peace of mind, legal protection, and critical information for planning and construction.
In Summary
A land surveyor plays an essential role in the property and construction industries. Their expertise ensures land is used, developed, and transferred correctly and legally. Whether you’re building a new home, planning a major project, or simply want to know exactly where your boundaries lie, a qualified land surveyor is the professional to call.
