I know this be a bit heretical, but I would prefer RA
1 Get agreement on common goals as to common style of play, get a plan together for a longer form Super Rugby - AU based or extension of current trans/NZ format, don't care, they need more games
2 Get a central contracting system - no warehousing (we don't have enough quality for the Tahs to have 3 good 10s or the ponies have a load of locks etc etc - I like the NZ system - each side picks a core 25, the rest are available to the other sides to become part of their 25), the states are a feeder system for the national side - simple
3 Get a director of rugby to implement the style of play, fitness expectations etc across the country (and fire those not meeting standards)
4 Get a national coach employed to coach the agreed style of play
