What infrastructure is required for my subdivision?

Infrastructure requirements for land subdivision in Australia are comprehensive, ensuring that every new lot is properly serviced and suitable for development or sale. These requirements protect buyers, maintain public health and safety, and satisfy council and servicing authority standards.

Key Infrastructure Requirements for Subdivision

Essential Services for Each Lot:

• Water: Every lot must have a reliable water supply. In urban zones, this means connection to mains water; rural lots may need rainwater tanks if reticulation is unavailable.

• Sewerage: Urban subdivisions must connect to council sewer systems. Rural lots often require on-site septic systems, supported by a soil suitability/geotechnical report.

• Stormwater Drainage: Every new lot must be properly drained. Urban areas require stormwater pipes to council mains or lawful discharge points; rural projects may need swales, detention basins, or other engineered solutions depending on site constraints.

• Electricity: Each lot must have access to metered electricity, usually via the extension of underground or overhead lines.

• NBN/Telecommunications: New lots must be able to connect to the National Broadband Network or another provider, with pit and pipe infrastructure or conduits installed as part of development works.

Access, Driveways, and Crossovers:

• All lots must have legal, all-weather access from a public road, often via a concrete crossover and driveway that meets council’s width and gradient standards.

• For battleaxe or flag lots, the access handle must be wide and compliant for vehicles and emergency/fire service access.

Fire Access (where required):

• In bushfire-prone areas, extra fire access and turning space, water supply (often a dedicated firefighting tank), and special driveway standards may be mandated.​

Other Common Requirements:

• Street lighting, kerb and channel in urban areas

• Vehicle crossings, footpaths, and sometimes verge landscaping

Rural/Non-Sewered Areas:

• Where mains services are not available, minimum requirements include large rainwater storage, on-site effluent management (septic or treatment plant), and sometimes backup power or satellite internet.
