Its remaining staff have been offered significant salary reductions or reduced hours after the coronavirus outbreak brought Super Rugby and the international game to a halt.
RA chief executive Raelene Castle has agreed to a 50 per cent pay cut, while other executives will receive 30 per cent less from April 1 until June 30.
Plans to launch a five-team domestic competition during the suspension of Super Rugby have been put on hold until at least May 1.
Castle said in a statement on Tuesday: "Today we have had to deliver the hardest news imaginable to our incredible, hard-working and passionate staff, that many of them will be stood down for a three-month period so that the game can survive this unprecedented crisis.
"Since the suspension of our proposed domestic Super Rugby competition, we have been working to understand both the immediate and long-term financial implications for the game as a result of the suspension of the competition, and potential further loss of revenue-generating content as we look ahead to the international season.
"Our extensive modelling shows that as a code, we could lose up to [AU]$120million in revenue should it not be possible for any rugby to be played in 2020. Of course, that is the worst-case scenario, and we are very hopeful that we can recommence the Super Rugby season and domestic Wallabies Test matches at some point this year.
"The measures we will implement from April 1, although extremely painful, are necessary to ensure the sport remains financially viable and to ensure that we are able to come out the other side of this global crisis, fully operational and ready to throw everything into the rebuild. It is our priority to keep all of our valued team connected and engaged through this period.
"We shared with the Rugby Union Players Association (RUPA) today the breadth of our cost-cutting including the standing down of 75 per cent of our staff. We will work closely with RUPA to reach an agreement which is appropriate given this unprecedented situation.
"I want to pay tribute to each and every member of staff across our rugby organisations and once again stress that once we get through this crisis, and we will, rugby will be back stronger than ever. All staff on stand down will have continued access to Rugby Australia support services during this time."
The Rebels and Brumbies announced all their employees would be stood down or continue with reduced pay until the end of June.
