Retaining Wall Costs Explained for Australian Home Owners (2025)

Retaining Wall Costs

Retaining walls is essential in landscaping, providing structural integrity and controlling erosion for outdoor spaces. Whether you’re managing steep slopes or creating level garden beds, understanding how much a retaining wall costs to build in Australia is important for budgeting.

Factors like materials, labour, and design complexity all influence the overall cost. For property owners in Albury-Wodonga, working with experienced retaining wall builders ensures a high-quality result tailored to your specific needs.

What Influences Retaining Wall Costs in Australia?

Linear wooden retaining wall made of horizontal timber planks, bordering a freshly mulched garden bed.

A major factor in the cost of making a retaining wall is the height and length of the retaining wall. This will directly affect the cost per square metre or linear foot.

Larger walls will require more materials and labour, thus increasing the project cost.


Another significant factor to consider is the soil itself. The soil type, steepness of slopes, and site accessibility all play a significant role in determining costs.

Challenging site conditions may require additional work, such as excavation or special drainage systems, to ensure the wall's stability.

The type of material used to create the wall is an important consideration when erecting a retaining wall.

Popular choices include natural stone, which offers a premium aesthetic but comes with higher material costs, or treated pine, which is a cost-effective option but less durable compared to other materials.

Other options include concrete sleepers, which are long-lasting and low maintenance, or reinforced concrete blocks, which are excellent for large-scale projects and steep slopes. Both are ideal for structural integrity.


It is also important to consider the drainage requirements of your block before selecting a material. Good drainage is critical for a long-lasting retaining wall.

Installing drainage systems to manage water flow adds to the overall cost but prevents expensive repairs in the future.

Average Retaining Wall Costs Based on Materials

Treated pine walls

Generally the cheapest retaining wall option, ranging from $150 to $300 per square metre. They are ideal for small retaining walls but require regular maintenance.

Concrete sleepers and poured concrete walls

Durable and long-lasting, these walls cost between $300 and $550 per square metre, making them suitable for heavy-duty applications.

Stone and sandstone walls

Provide unmatched aesthetic appeal but can cost between $400 and $800 per square metre due to the premium materials used.

Cinder blocks and reinforced concrete blocks

Cost-effective investment for steep slopes and large projects, these materials range from $250 to $450 per square metre.

Additional Costs to Consider in a Retaining Wall Project

Council Approval

Local council regulations may require approvals for certain wall types, which can add to the project’s timeline and cost.

Labour Costs

Hiring skilled wall contractors and structural engineers is crucial for maintaining safety and quality, with labour costs making up a significant portion of the budget.

Drainage Systems

Drainage installation ensures proper water flow and prevents damage, adding to the initial investment but saving money in the long term.

Site Accessibility

Difficult-to-reach sites or those with steep slopes may require additional equipment or time, increasing the overall cost.
