Department of Transport and Planning

The Department of Transport and Planning (DTP) is a government department in Victoria, Australia. Commencing operation on 1 January 2019 as the Department of Transport (DOT), the DOT was formed in machinery of government changes made by Premier Daniel Andrews after the re-election of his Labor government at the 2018 Victorian state election. The re-shuffle saw the "super-ministry" Department of Economic Development, Jobs, Transport and Resources abolished and its functions reassigned to the DOT and Department of Jobs, Precincts and Regions.

The department is responsible for ongoing operation and coordination of the state's transport networks, as well as the delivery of new and upgraded transport infrastructure. As part of a major restructure of the legislative and organisational structure of the state's transport sector between 2019 and 2022, the department absorbed the statutory responsibilities and staff of the formerly independent agencies VicRoads and Public Transport Victoria, and from 2024 began providing public-facing transport information under the brand Transport Victoria.

On 1 January 2023, after the 2022 Victorian state election, the department absorbed the planning functions of Department of Environment, Land, Water and Planning and was renamed to its current name.

The DTP supports three ministers in the first Allan ministry, holding three ministerial portfolios: Minister for Ports and Freight and Minister for Roads and Road Safety Melissa Horne, Minister for Public and Active Transport Gabrielle Williams, Minister for Planning Sonya Kilkenny.
