"Next year there's going to be a fourth Super 12 team and that increases your player pool by another 30 professional players. And that's going to help the Wallabies immensely over time," he said.
"And with the new provincial set up... the more games guys get at that high level, especially those guys who are on the fringe, it will definitely help the player pool."
Flatley also believes that the new format of the Tri-Nations series, which will feature three matches against both New Zealand and South Africa, will give Wallaby players a better chance to prove themselves and will also give a fairer indication of who is the best team in the Southern Hemisphere.
"I think it's a good way to have it. Whoever wins one game, it's whoever owns the trophy from the previous year. So this way you get a clear cut winner," he said.
"They're pretty big games, the Bledisloes, and it does take a lot out of you as a player. But I'm sure the players will get used to it. They're the games we love playing, the big games and that's what every rugby player wants to be involved in."
