Rugby Australia's Mosman connections continue to deliver for the game, with Peter Wiggs one of the leading candidates to fill the governing body's leadership void following the sudden resignation of Raelene Castle.

Wiggs, an economics graduate of Sydney University who went on to found private equity fund Archer Capital, has been on the RA board for just three weeks. Yet in that time the former Mosman winger, who counts former Wallabies captain Phil Kearns and Australian Olympic Committee boss Matt Carroll among his associates, appears to have made himself indispensable to the organisation.

Wiggs was the circuit breaker in RA's protracted pay deal negotiations with the players union, replacing former RA director Brett Robinson at the table and quickly working through the flashpoints to clinch an overall 83 per cent reduction in the player wages bill. He also led Thursday night's meeting between RA and the Super Rugby chairmen, at which chief financial officer Simon Rabbitt was expected to open the books to the states for the first time.

Wiggs' contribution in a short space of time has many traditionally disparate voices privately singing his praises, from former RA chief executive Raelene Castle to the Super Rugby chairs, the players union and other state administrators.
