The Department of Planning, Transport and Infrastructure is undertaking a Planning Study for the duplication of Main South Road. The Main South Road Duplication will be delivered in two stages:

Stage 1: Seaford to Aldinga. This has been identified as a priority and the State Government is investing $305 million for Stage 1

Stage 2: Aldinga to Sellicks Beach.

The study covers both stages of the project and will include an evidence-based concept plan for Stage 1 (Seaford to Aldinga) that is informed by consultation with stakeholders.

Stakeholder and community engagement forms an important part of the study and we value your input. As a key stakeholder/landowner we invite you to provide your input by 31 July 2019.

For more information and to provide feedback, comments or register your interest, you can email, complete a feedback form at or call 1300 794 880.
