Service providers
Following an extensive procurement process and consultation with industry, road maintenance contracts were awarded to a number of providers. The initial term of contract is 7 years from the contract's start date. There is provision to extend for up to a further 6 years (+3 +3 years).
On 2 March 2026, Downer EDI Works Limited (Downer) took full operational control of the Regional South (Zone 2) road maintenance contract. Downer will ensure the continuity of road maintenance services for Zone 2 for the remainder of the contract term, which expires in November 2027. This change follows a transition period between the Department, Fulton Hogan and Downer.
