Fencing Calculator
Calculate materials (posts, rails, palings/panels) and cost for timber, Colorbond, or pool fencing.
How this calculator works
Calculates the number of posts (length / spacing + 1), rails (typically 2-3 per bay), and palings or panels per bay. Includes gate hardware and concrete for post footings. Multiplies by unit costs for a materials breakdown, or uses cost-per-metre for a quick total estimate.
Standard residential: 1800mm. Pool: 1200mm minimum.
Standard spacing: 2400mm (2.4m) for most fencing
Pedestrian or vehicle gates
Colorbond: $100-$150/m. Timber: $75-$120/m. Pool glass: $300-$600/m.

FAQ
Frequently asked questions
How much does Colorbond fencing cost in Australia?
Colorbond fencing costs approximately $100-$150 per lineal metre installed (1800mm height). DIY materials only cost $65-$90/m. Prices vary by region โ metro areas are typically cheaper than rural due to competition and transport.
What are the fencing laws in Australia?
Boundary fences are generally shared responsibility (50/50) between neighbours under each state's fencing act. Height limits vary by council but standard residential is 1.8m (rear/side) and 1.2m (front). Always check with your local council.
What depth should fence posts be?
Fence posts should be set at least 600mm deep (a third of the total post length). In soft or sandy soil, go deeper (750-900mm). Posts should be set in concrete (1-2 bags per post). End and corner posts may need bracing.
What is the minimum pool fence height?
Under AS 1926.1, pool fencing must be at least 1200mm high with no climbable objects within 900mm. Gates must be self-closing and self-latching, opening outward from the pool. Non-climbable zone (NCZ) requirements apply to all pool barriers.
