Answer:
Yes — you may provide your own site reports, but they must be current, council-recognised, and compliant with NCC standards.

You can supply:

• Soil test (geotechnical report)
• Contour or topographical survey
• Bushfire, flood, or acoustic overlays (if applicable)

If you don’t have these, Expandify can organise them on your behalf through trusted professionals. We will assess your existing reports for suitability before confirming the next steps in the approval process.
