Timber sleepers ($215–$485/lm in Townsville) are cheapest. Concrete sleepers ($270–$650/lm) are the most popular. Sandstone ($380–$755/lm) is premium but looks great.
Wall height
Walls under 1m are straightforward. Walls over 1m in Townsville typically need stronger footings. Over 1.5m requires structural engineering certification.
Engineering requirements
Walls over 600mm (some Townsville councils) or 1m (others) need a structural engineer's design ($540–$2,150). This adds cost but is legally required and protects you.
Drainage
Every retaining wall needs drainage behind it ($32–$86/lm in Townsville). Without proper drainage, water pressure builds up and the wall can fail within a few years.
Site access
Easy access for a small excavator in your Townsville property keeps costs low. If materials need to be carried by hand (steep slopes, narrow access), costs increase significantly.
Existing wall removal
Demolishing and removing an old failed wall in Townsville costs $50–$180/lm on top of the new wall cost.

Side-by-side guides covering the decisions that most change your final retaining wall cost.
How much does a retaining wall cost per metre in Townsville?
A retaining wall in Townsville costs $215–$485/lm for timber sleepers, $270–$650/lm for concrete sleepers, and $380–$755/lm for sandstone (all at approximately 1m height including footings).
How much does a 10m retaining wall cost in Townsville?
A 10-metre retaining wall at 1m height costs $2,700–$7,550 in Townsville, depending on the material chosen, site conditions, and drainage requirements.
Do I need council approval for a retaining wall?
In most Townsville councils, walls over 600mm–1m require a development application. Walls over 1.5m almost always need engineering certification and council approval. Always check with your local council first.
What's the best material for a retaining wall?
Concrete sleepers offer the best value — they're durable, low-maintenance, and look good. They cost $270–$650/lm in Townsville. Timber is cheapest but has a shorter lifespan (15–20 years vs 50+ for concrete).
How long does a retaining wall last?
Timber sleeper walls last 15–25 years. Concrete sleeper and block walls last 50+ years. Sandstone and boulder walls can last indefinitely with proper drainage. The biggest factor is drainage — poor drainage is the #1 cause of wall failure.
Can I build a retaining wall myself?
Small walls under 600mm are a feasible DIY project. Anything taller in Townsville should be done by a professional — the weight of retained earth is enormous and failure can damage property or cause injury.
