Some lots may require minimum infrastructure, such as a new sewer and water connections on existing mains, electricity or phone services. Others may need more substantial upgrades such as footpaths, water and sewer extensions and underground electricity connections. These, and many other, factors impact the cost of subdivision.
Under the Adopted Infrastructure Charges Regime (AICR), the maximum infrastructure charge is $30,226.70 per additional allotment although some council areas levy less than this amount. The estimated cost for the entire subdivision process, including infrastructure charges, statutory fees, civil works, and consultants is usually between $70,000–$90,000* based on some general rules of thumb. However, each subdivision requires its own financial analysis and feasibility, as costs in some cases can exceed this cost range.
The reason for such a broad range is required civil works on each project can vary significantly. Even two projects, which look the same, can have a significantly different costs.
