What is a Quantity Surveyor?

If you’ve ever wondered who keeps construction budgets on track—or how investors know exactly what to claim at tax time—it often comes down to one professional: the quantity surveyor.

A quantity surveyor is a qualified expert in construction costs, budgeting, and property tax depreciation. Whether you’re building, renovating, or investing in property, a quantity surveyor ensures you’re not overspending—and that you’re claiming every dollar you’re entitled to.

At Quantity Surveyors Australia, we help clients across the country with everything from building cost estimates to ATO-compliant tax depreciation schedules. Our job is to make sure the numbers work for your construction project, your investment, and your peace of mind.

If you’ve recently purchased an investment property—or if you haven’t yet claimed depreciation—you may be leaving money on the table.
