"RUPA launches the 'Stronger as Five' petition today to constructively bring together that support from all over the country.
"Without a final decision having been made by SANZAAR and the ARU, we encourage the rugby community to show their support for the vibrant, aspirational and successful five-team future that Australian rugby deserves."
The micro-site also details concerns that RUPA has regarding the impacts of any reduction, including weakened economic potential, decreased playing and coaching opportunities, and the protection of expansion teams in Argentina and Japan at the expense of Australian teams.
RUPA says "all of Australia's rugby players remain staunchly united in their opposition to any mooted alternative models which would reduce Australia's representation in the Super Rugby competition for 2018 and beyond, a point made last month prior to the SANZAAR Executive Committee meeting in London.
"This petition provides a genuine opportunity for fans, coaches and administrators to join with the players, and influence one of the most critical decisions in the game's history in Australia.
"It's time for Australian Rugby to make a comeback; not a cut back. We are 'Stronger as Five'."
