The Australian Government has committed $5.9 billion to the Roads of Strategic Importance (ROSI) initiative to help connect regional businesses to local and international markets, and better connect regional communities.

ROSI is ensuring our key freight roads efficiently connect areas of regional and remote economic activity to ports, airports and other transport hubs. This initiative is delivering works such as road sealing, flood immunity, strengthening and widening, pavement rehabilitation, bridge and culvert upgrades and road realignments.

Improved access provided through ROSI is providing substantial social and economic benefits, including opportunities for greater regional employment and business growth.
