Boundary & Cadastral Survey Services in Sydney & Greater NSW
Precise Boundaries. Reliable Data. Trusted Surveyors.
At Astra Spatial, we deliver boundary and cadastral surveys that provide legal certainty for landowners, builders, architects, and developers.
Operating across the Sydney & Eastern Suburbs, North Shore, Inner West, Parramatta and the wider Greater Sydney region, our licensed cadastral surveyors use modern total‑station technology to establish, mark and document exact property boundaries in compliance with state surveying legislation.
Why Boundary & Cadastral Surveys Matter in Sydney
Accurate boundary data is essential for land transactions, subdivision design, fencing, or construction close to property limits.
A cadastral survey defines those legal boundaries, while a boundary survey re‑establishes them on the ground.
A professionally certified boundary survey in Sydney or greater NSW protects against:
- Encroachment disputes with neighbours
- Rejected development or subdivision applications
- Expensive rework due to incorrect boundary placement
Astra Spatial’s team has surveyed everything from residential allotments in North Sydney, the Hills District, and the Inner West to large commercial and subdivision projects throughout Parramatta, South West Sydney, and regional NSW.
Our Sydney Boundary & Cadastral Survey Process
1 | Pre‑Survey Assessment
We review registered plans, title documents, easements and survey control marks to determine the legal reference points for your property.
2 | Field Survey & Re‑Establishment
Using total stations, we conduct on‑site measurements to re-establish the true boundary positions.
3 | Data Processing & Validation
All field data is processed through our cadastral software and validated against official state survey infrastructure records.
4 | Boundary Marking & Documentation
We mark the boundary corners and supply certified plans for submission to NSW Land Registry Services.
5 | Delivery & Consultation
Your registered surveyor reviews the findings, answers questions, and provides digital deliverables for architects, builders, and legal teams.

How accurate are your surveys?
All boundary and cadastral surveys are performed using calibrated total station equipment referenced to official state survey control.
What does a boundary re‑establishment survey cost?
