Roads of Strategic Importance
The Australian Government will invest $4.5 billion, including $1 billion of additional funding committed in the 2019-20 Budget, to the Roads of Strategic Importance (ROSI) initiative to help connect regional businesses to local and international markets, and better connect regional communities.
ROSI will ensure our key freight roads efficiently connect agricultural and mining regions to ports, airports and other transport hubs. It will deliver works such as road sealing, flood immunity, strengthening and widening, pavement rehabilitation, bridge and culvert upgrades and road realignments.
Improved access provided through ROSI will deliver substantial social and economic benefits, including opportunities for greater regional employment and business growth.
On 13 October 2018, the Government released the ROSI Investment Principles PDF: 1168 KB 
, which set out the objectives for investment through ROSI.
ROSI funding will be used to upgrade the following freight routes across Australia:
