The Northern Territory will join the ACT and South Australia in lobbying for a national space agency.
Northern Territory Chief Minister Michael Gunner will sign his government up to an existing memorandum of understanding between the latter states at the International Astronautical Congress in Adelaide on Monday.
Each jurisdiction will offer their assets and capabilities to help bolster Australia's space standing. Canberra has offered brains, South Australia land and research, and the Northern Territory its vast land primed for launch.
The state and territories will jointly lobby the federal government to increase Australia's international standing in the area.
ACT Chief Minister Andrew Barr last month called on the Commonwealth to better support the development of Australia's space industry.
"This agreement will further the capabilities of the ACT's space industry and will help create more jobs," he said on Sunday.
"The inclusion of the Northern Territory into the agreement the ACT signed with South Australia just a few weeks ago is a sign of the growing importance of the space industry in creating new jobs across the country.
"During the congress, I will also meet with leading ACT based companies operating in the industry including SpaceX, Northrop Grumman Australia and Lockheed Martin to discuss opportunities for the ACT Government to assist the industry to grow."
The federal government announced a review into Australia's space capabilities in July.
