Roads of Strategic Importance (ROSI) is a $5.8 billion initiative of the Australian Government designed to help connect regional businesses to local and international markets, and to better connect regional communities. The source for this article is an Australian Government website titled "Roads of Strategic Importance". Funding by the Australian Government is up to 80% of total costs, with the remainder being met by state, territory and local governments. ROSI reserves $1.5 billion for projects in Northern Australia, building on the benefits being delivered by the Northern Australia Roads Program and the Northern Australia Beef Roads Program.

Types of work
ROSI is ensuring that key freight roads efficiently connect agricultural and mining regions to ports, airports and other transport hubs. The work undertaken includes bridge and culvert construction, road widening, sealing, overtaking lanes and pavement renewal.

Strategic corridors
Most ROSI projects are grouped within defined corridors, which are listed separately in alphabetic sequence for each of Northern and Southern Australia. A corridor includes roads and related infrastructure associated with the efficient operation of the principal highway or road in the corridor. Each corridor listed contains zero to many projects, some of which pertain to a single road  while others cover multiple roads and/or related infrastructure.

Other States details copied to articles

For all states and territories except the Australian Capital Territory there are ROSI projects for one or more roads in each of one or more strategic corridors, plus a number of non-corridor projects for all but Tasmania, the ACT and the Northern Territory. Some of the subject roads have Wikipedia articles that should be updated with details of the relevant project/s. The approximate number of projects listed for each state or territory is as follows:
