How the IC team can help you​

On behalf of the DBNGP Land Access Minister, the Infrastructure Corridors team manages the corridor land that houses the DBNGP and other high pressure gas pipelines. This role is distinct from that of the pipeline owners or licencees, who are responsible for the operation of the pipeline and maintaining its safety and integrity.



Work processes IC team manages under DBPA


Member of the Dial Before You Dig (DBYD) service


The Department of Lands (DoL) is a member of the DBYD national referral service as we manage land containing vital underground assets. Since July 2014, the DoL has implemented an automated response service. DoL also reminds proponents of the need to seek statutory approval from the DBNGP Land Access Minister before commencing non-pipeline related works within the DBNGP corridor.

Approval for non-pipeline related works within the DBNGP corridor (s. 41 approval under DBPA)


Property owners, pipeline operators and third parties must seek approval from the DBNGP Land Access Minister under section 41 of the DBPA to carry out non-pipeline related works within the DBNGP corridor. Please refer to the Land Use Guidelines for further information.

The approval process generally takes three to four weeks as we may seek advice and comment from other agencies or pipeline operators. This approvals process ensures any works that are carried out within the DBNGP corridor does not compromise the safety and integrity of the DBNGP and other vital gas pipelines.

Approval for pipeline related works within the DBNGP corridor (s. 34 of DBPA)


If you are a pipeline owner/operator, the DBNGP Land Access Minister may confer Access Rights under s. 34 of the DBPA to construct gas pipelines within the DBNGP corridor. The Access Right allows you to construct, test, maintain, repair or enhance high pressure gas pipelines or for any incidental purpose and are non-exclusive. The Access Rights are conferred for a fixed term.

Referral agency in the WAPC approvals process


Under the DBPA, no other statutory agency has authority over land within the DBNGP corridor. Therefore, the DoL is a referral agency for the Western Australian Planning Commission (WAPC) and Local Government Authorities (LGAs). The WAPC and LGAs refer any planning or development application which includes land within or in close proximity to the DBNGP corridor to the DoL for comments. DoL assesses the application based on compliance with the DBPA, restrictions under registered easement documents, and pipeline safety and integrity.

DBNGP corridor widening - South West widening


In 1998, Cabinet endorsed an initiative to widen the DBNGP corridor allowing the security of land tenure to install additional pipelines to service future needs of Western Australia. The generalised width of the DBNGP corridor varies as follows:

Dampier to Bullsbrook: 100m
Within the Perth metropolitan area: 30m
Kwinana to Bristol Road (Waroona): 30 to 50m
Bristol Road (Waroona) to Clifton Road (Brunswick): 16 to 30m


DoL is currently completing the South West widening project in two stages:

  • Kwinana to Bristol Road (Waroona)

    The DoL has successfully negotiated with many of the landowners affected by the widening project for the acquisition of State corridor rights over portions of the DBNGP corridor.
  • Bristol Road (Waroona) to Clifton Road (Brunswick)

    Due to environmental values of the wetlands through Kemerton, the DoL needs to complete an environmental impact assessment to meet the Environmental Protection Act 1986. The DoL has developed the following documents to provide additional information on this project.
