Don't think these Wallabies are a class team, they are a team with a bunch of fairly decent players, but this is international rugby and you need outstanding players at most positions to compete.
How many Wallabies would make the Boks or the ABs, or forecast to do so in the next few years?
At most: Skeleton (reserve lock) who isn't playing for OZ, Tupou, and honestly that's about it.
Kerevi/Korobiete might get a look in, but I think they'd get the Laumape treatment where they are not selected as a first choice player as the rest of their game isn't well rounded. I think Hooper gets the Matt Todd treatment and isn't picked over PSDT, Cane, Ardie etc., likely plays about the same as Kwagga Smith/Matt Todd.
Guys like Banks, Lolesio, Hodge, Paisami, Wilson, Uelese, are good players, but they are not going to make a major mark at test rugby.
