There is no info on the Australian Rugby Football Schools Union site (
http://austschools.rugbynet.com.au/ ) on the change of policy however it was broadcast infinitum during the Qld trials that for the first time players from Qld and NSW not making their respective state teams were eligible for inclusion in the Combined States team. That team we were told was to be announced today.
I can think of a couple of lads who would be holding their breath for that opportunity.
As for the strength of the two teams, in my opinion the Qld I team is by far the stronger on paper. As mentioned before, none of the AIC players really stood out sufficiently to supplant the GPS players so the Qld II team I would hope are very strong on teamwork rather than individual ability. Having said that I am sure they represent a serious threat to anyone playing them for that reason.
