When embarking on a property project – whether you’re building your dream home, subdividing land, or investing in commercial real estate – a Registered Surveyor is your trusted professional to ensure accuracy, compliance, and peace of mind.
But what exactly is a Registered Surveyor, and why is hiring one essential in Sydney and throughout New South Wales? Let’s break it down in this comprehensive guide.

What is Land Surveying?
Land surveying is the scientific method of measuring and mapping environments, properties, and features on or beneath the Earth’s surface. Surveyors determine boundaries, create maps, assess terrain, and establish the legal framework essential for all property transactions and developments.

What is a Registered Surveyor?
A Registered Surveyor is a land surveying professional legally authorised by the Board of Surveying and Spatial Information (BOSSI) in NSW to define property boundaries and provide official land surveys. This is the highest level of professional accreditation in land surveying in New South Wales.
Registered Surveyors have the authority and expertise to:
- Carry out boundary (cadastral) surveys
- Prepare and certify subdivision plans
- Perform strata and community title surveys
- Provide legally recognised boundary reports and certificates
- Create accurate topographic and site detail surveys
📌 Important:
Only a Registered Surveyor can legally perform boundary surveys and lodge plans with NSW Land Registry Services.
How Do You Become a Registered Surveyor?
To become a registered in NSW, professionals must meet rigorous criteria set by BOSSI:
- Educational Qualifications: Hold an accredited tertiary degree in surveying (typically a Bachelor of Surveying).
- Professional Experience: Complete a minimum of two years supervised practical training under a Registered Surveyor
- Examinations: Pass a series of challenging BOSSI examinations in cadastral surveying, planning, engineering, and legal principles related to land subdivision and surveying practice.
Only after successfully meeting these criteria is a surveyor officially “Registered.”
Maintaining Registration: Continuing Professional Development
Once registered, surveyors must actively maintain their status by:
- Paying an annual registration fee.
- Completing mandatory Continuing Professional Development (CPD) each year, which includes attending workshops, seminars, and training sessions.
- Demonstrating ongoing competence and staying current with updates in surveying technologies, laws, and regulations.
These strict ongoing requirements ensure surveyors remain at the cutting edge of their profession, delivering accurate and compliant surveys consistently.

Why Using a Registered Surveyor is Beneficial
Engaging a Registered Surveyor provides numerous benefits, including:
- Legal Protection:
Accurate boundary definitions protect you from disputes, legal liabilities, and potential financial losses.
- Project Compliance:
Streamlined council approvals (DA and CDC), ensuring your project meets NSW zoning and development standards.
- Cost Savings:
Avoid costly mistakes and disputes by getting your boundaries and project data right the first time.
- Enhanced Property Value:
Accurate and certified property boundaries and subdivision plans enhance your property’s market value and buyer confidence.
- Expert Guidance:
Access to professional advice on navigating complex planning, zoning, and regulatory requirements.

The Legal Risks of Not Using a Registered Surveyor
In NSW, performing boundary surveys or lodging subdivision plans without being a Registered Surveyor isn’t just risky – it’s illegal. Work conducted by an unregistered person has no legal standing, no insurance cover, and exposes property owners to severe risks:
- Boundary inaccuracies that could trigger neighbour disputes.
- Development application rejections by councils, delaying projects.
- Costly litigation or fines due to non-compliance with property laws.
- Project stoppage or demolition orders, resulting in significant financial losses.
In short: hiring anyone other than a Registered Surveyor could jeopardise your entire investment.

How a Registered Surveyor Can Save You Money
Hiring a Registered Surveyor isn’t just about compliance – it’s a financially prudent choice:
- Avoid Boundary Errors:
Accurate boundaries prevent costly modifications and boundary disputes.
- Accelerate Approvals:
Clearly defined surveys speed up council approvals, saving substantial time and money.
- Insurance Coverage:
Registered Surveyors carry professional indemnity insurance, protecting you from liability due to survey errors.
- Identify Hidden Risks:
Detect property limitations early, such as easements or covenants, avoiding unexpected expenses later.

Licensed Surveyor vs. Registered Surveyor: What’s the Difference?
In Australia, the terms “licensed surveyor” and “registered surveyor” both indicate the highest level of professional certification in land surveying – but terminology differs between states.
- New South Wales: Called “Registered Surveyors” (accredited by BOSSI).
- Victoria: Called “Licensed Surveyors”.
Regardless of the title, both terms represent equally high professional standards, ensuring the surveyor has passed strict education, experience, and examination criteria.
Common Mistakes When Hiring a Surveyor (and How to Avoid Them)
Avoid these pitfalls to protect your project:
- Not Checking Registration Status:
Always verify registration through BOSSI’s official registry.
- Misunderstanding the Survey Type Required:
Clearly discuss your project needs to ensure the correct type of survey is performed (Boundary, Detail, Subdivision, etc.).
- Ignoring Council Requirements:
Ensure your survey meets council or private certifier standards before proceeding with development applications.

Real-World Example: Avoiding Costly Disputes
A Sydney developer once built without consulting a Registered Surveyor and discovered – six months later – their building encroached onto neighbouring land.
Consequences:
- Costly legal disputes, fines, and project delays.
- Structural modifications costing tens of thousands.
Solution:
A Registered Surveyor was later engaged to rectify the problem, define correct boundaries, and resubmit subdivision plans – allowing the project to proceed legally.
Lesson Learned:
Early engagement of a Registered Surveyor prevents expensive disputes, legal headaches, and project delays.
