Nationally, a 10 m wall retaining 1.0 m lands between about A$3,800 and A$14,300 installed depending on system and site.

What to check at the property
- Whether the project is new, repair, replacement or an addition to an existing wall.
- Retained height, nearby buildings, other walls and surcharge loads.
- Fence, slab, pool, tank, garden bed or additional fill above the wall.
- Boundary position and the landowner benefiting from the retained level.
- Collection and lawful discharge of surface water and subsoil seepage.
How to make Sunshine Coast quotes more comparable
Sunshine Coast proposals should distinguish modification from minor maintenance, state who appoints the private building certifier and describe drainage as capture, conveyance and discharge rather than a pipe allowance alone.
Keep demolition, spoil, access, drainage, professional work, approvals, GST, provisional items and exclusions visible as separate scope fields.
