How much does a structural engineer cost?
Structural engineers in Australia typically charge $400–$1,000 for a site inspection and report, $800–$2,200 for beam or wall-removal design, and $2,500+ for full extension or new-build design.

What affects the price
— Scope of engineering. A single beam is quick; a whole extension or two-storey design takes many more hours.
— Site investigation needs. If a geotechnical (soil) report is required, it's a separate cost of roughly $600–$1,500.
— Existing documentation. Missing original plans mean the engineer must measure and model the existing structure first.
— Complexity & risk. Sloping sites, reactive soils, heritage buildings and unusual designs add analysis time.
— Turnaround time. Urgent reports and designs often attract a priority fee.
Tips before you post
— Check the engineer is registered where required — most states now mandate registration (RPEQ, PE registration or equivalent) for structural work.
— Engage the engineer before removing anything that might be load-bearing — retrofitting a fix costs far more than designing it first.
— Ask whether council or certifier queries after lodgement are covered in the fixed fee.
