The Department is working towards creating well-connected, well-serviced communities to accommodate Sydney’s growing population. The Special Infrastructure Contribution (SIC) framework is one of many initiatives in place to help ensure the demands of the growing population are met in a timely manner.

A Special Infrastructure Contribution is paid by developers to share the cost of delivering the infrastructure required to support growing communities. The SIC funds infrastructure such as schools, State and regional roads, regional open space, emergency and health facilities, and some public transport infrastructure.

Contributions are collected for new developments within a defined boundary called the Special Contributions Area (SCA). SICs are currently being prepared and proposed for all Planned Precincts and Growth Areas across Sydney. 

The SIC is based on strategic planning for the contribution area. The infrastructure schedule identifies the key pieces of infrastructure that can be delivered by SIC funding, and the SIC rate is the per-dwelling or per-lot portion of the total infrastructure cost that must be paid by developers. 

The Department will also consider development feasibility in setting a SIC charge so that the SIC will not impact housing supply. The SIC framework will be reviewed regularly with the rate subject to indexation.

Planning for growth in the Wilton Growth Area forms part of the Government’s broader strategic planning for Sydney. The Greater Sydney Region Plan provides high level strategic guidance which identifies Wilton as a Growth Area with strong presence in South Western Sydney, becoming a focal point in the Western Parkland City. To complement these strategic plans, we’ve been working on:

  • Wilton 2040 (a plan for the Wilton Growth Area)
  • Draft Special Infrastructure Contribution (SIC) for Wilton

Wilton 2040 identifies the major items of state and local infrastructure required to be put in place as Wilton grows and which will best meet the community's needs into the future, while retaining the elements that make it a special place now. The role of the Special Infrastructure Contribution is to fund key projects identified in the plan, providing certainty about delivering infrastructure that will support new jobs, homes and services as the community grows.

Special Infrastructure Contributions to be paid by developers will contribute to the cost of delivering infrastructure to support new homes across the Wilton Growth Area, estimated to be $771 million over the next 20-30 years, including:

  • Roads, intersections, bridges and cycleway improvements - $655 million
  • Biodiversity conservation and regional open space - $65 million
  • Education - $31.25 million
  • Public transport facilities - $5 million
  • Health and emergency service facilities - $1.375 million
  • Planning and delivery - $14 million

The proposed Special Contribution Area (SCA) is the boundary in which the SIC will apply. The Wilton SCA is pictured below:

The proposed Special Contribution Area (SCA) for the Wilton SIC is shaded in pink on the map.


A rate of $59,274 per additional dwelling or lot within the SCA will apply.

The Bingara Gorge precinct is not included in the SCA boundary as contributions to state and regional infrastructure have been set out in an earlier Voluntary Planning Agreement.

The rezoning of land means a significant increase in the demand for new and upgraded infrastructure across Wilton. A coordinated approach is essential for funding the delivery of new and upgraded infrastructure in line with population growth.
The SIC will ensure infrastructure such as schools, health, emergency and public transport facilities, open space, road and cycle path upgrades will be coordinated and delivered at the same pace as new homes and jobs, to support the growing community’s needs.

The Department will coordinate with infrastructure agencies and Council to best prioritise funds collected from the Wilton SIC towards the infrastructure projects identified. 

The early development of Wilton will be through developers entering into voluntary planning agreements with the Department. A key component of these agreements will be the delivery of infrastructure as works in kind. The works in kind agreements define the regional infrastructure to be funded and delivered by the developer in line with approvals for a specific numbers of dwellings. This means that infrastructure will be delivered in line with or in advance of the delivery of housing.

Anyone who is developing and delivering new residential dwellings within the Wilton Special Contribution Area will pay a Special Infrastructure Contribution to the state government. Tenants and small businesses will not be affected by the SIC.
Exemptions are proposed for development of social housing, seniors housing or affordable housing carried out by or on behalf of a community housing provider. The contribution does not apply to employment or commercial land, except for development in mixed-use zones where residential accommodation is provided.

The SIC framework has many benefits for the community, landowners, councils and developers:

  • Provides certainty to the community that the infrastructure identified in the precinct plan will be funded and delivered;
  • Offers transparency about the collection and distribution of funds for required infrastructure;
  • Streamlines the planning process;
  • Ensures the timely delivery of infrastructure in line with community expectations and rate of growth;
  • Provides certainty for business, councils and community that infrastructure is funded and will be provided alongside or soon after new developments; and 
  • Enables developers to contribute funding towards infrastructure that provides a direct benefit to the community and adds value to the development.

Special Infrastructure Contributions fund state and regional infrastructure which means a SIC may only be determined by the Minister for Planning.


Section 7.11 and Section 7.12 contributions plans are made by local government authorities to assist them with funding local infrastructure items within a local government area. This funding allows the delivery of local facilities and services such as local roads, local open space and community facilities such as libraries. These services are typically the responsibility of local government.

Infrastructure contained in a local contributions plan will be different to that contained in a SIC infrastructure list.

The SIC is paid by developers to the state government during the development application (DA) process. Alternatively, developers may seek approval from the Minister for Planning to dedicate land for required infrastructure or build a piece of required infrastructure, instead of making a financial contribution. The delivery of infrastructure instead of a cash contribution is known as a works-in-kind agreement.

The Ministerial Determination is the legal document that allows a Special Infrastructure Contribution to be levied on development within a contribution area under The Environmental Planning and Assessment Act 1979. An individual Determination must be made for each area where a SIC is proposed, signed by the Minister for Planning and published in the Government Gazette before it can be applied. 
Once the Determination is made the Minister will issue a direction to local councils to impose the contribution as a condition of consent on all resident development applications.

The proposed SIC for Wilton is currently on exhibition and you are encouraged to provide feedback on the proposed rate, contribution area and infrastructure schedule until 9 November 2018.

The Department has identified the need for infrastructure costs contained within the schedule to keep pace with annual changes in the cost of land and construction services. 

The proposed indexation of the Wilton SIC will be based on the Producer Price Index.
