Infrastructure Charges in Queensland: The Six-Figure Cost Developers Miss

Infrastructure charges are one of the most consistently underestimated costs in Queensland development feasibility analyses. They are not a building cost, not a planning cost, and not a finance cost. They are a statutory levy imposed by local and state government on development that creates additional demand for public infrastructure.

For residential subdivision projects in Brisbane, infrastructure charges can represent $30,000 to $80,000 per lot created, a cost that directly reduces the financial viability of any project where it is not accurately accounted for in the land acquisition price.

Infrastructure charges in Queensland are levied under the Planning Act 2016. They are contributions by developers toward the cost of infrastructure that the community must provide to service the additional population created by their development. The infrastructure covered includes roads, water supply, sewerage, stormwater management, parks, and community facilities.

The charges are set out in an Adopted Infrastructure Charges Notice (AICN) or an Infrastructure Charges Schedule for each local government area. Brisbane City Council maintains its own infrastructure charges schedule, which is publicly available on council's website.

The charges are calculated based on the type and scale of development, the location within the infrastructure network planning areas, and any applicable offsets for infrastructure already provided by the developer or existing on the site.

For residential development in Brisbane, infrastructure charges are calculated on a per-dwelling or per-lot basis, depending on the development type.

For a dual occupancy on an existing lot, the infrastructure charge applies to the additional dwelling unit created (the existing dwelling's infrastructure charge is assumed to have been paid at the time of the original subdivision). In Brisbane, the charge for an additional dwelling unit in most residential areas ranges from approximately $28,000 to $50,000 depending on location and the specific infrastructure catchments applicable.

For subdivision projects creating multiple new lots, each new lot beyond the existing entitlement attracts an infrastructure charge. A subdivision creating 10 new lots in Brisbane might attract total infrastructure charges of $300,000 to $500,000.

For medium-density apartment or townhouse developments, charges are calculated per bedroom or per dwelling unit depending on the applicable schedule.

The infrastructure charges framework allows for offsets where a developer is providing infrastructure that would otherwise be funded from the charge pool. Common offsets include the construction of public roads, sewer mains, or stormwater infrastructure beyond what is strictly required for the development.

Credits may also apply where the site already has an existing infrastructure charge credit from a previous development approval.

Calculating the net infrastructure charge payable, accounting for any offsets and credits, requires careful analysis of the applicable schedule and the development proposal's infrastructure contributions.

Infrastructure charges should be included as a development cost in any feasibility model from the earliest stages of site assessment. A preliminary estimate can be calculated using the published infrastructure charges schedule and the proposed development yield.

For any site where subdivision or multiple dwelling development is being considered, prepare an infrastructure charges estimate before committing to a purchase price. The charges are a fixed cost of development that cannot be negotiated with council once the development approval is issued.
