What affects the price

— Wall face area. Length times height is the core quantity — taller walls also need heavier posts and footings.

— Material. Treated timber is cheapest but has the shortest life; concrete sleepers and masonry cost more and last decades.

— Engineering & approvals. Walls above roughly 1 m usually need an engineer's design and council sign-off, adding $1,500–$4,000.

— Drainage & backfill. Ag-pipe, gravel backfill and stormwater connection are essential and add real cost.

— Access & excavation. Machine access keeps digging cheap; hand excavation on tight sites multiplies labour.

Tips before you post

— Check your council's height threshold before designing — approval requirements kick in at 0.5 m in some areas.

— Never skip the drainage behind the wall; water pressure is what destroys retaining walls.

— Concrete sleepers cost more than timber upfront but usually work out cheaper over the life of the wall.
