It turns out, I think, that the Presidents XV play int the inaugural NSW Invitational:

Being in it's first year The whole thing about this 16's invitational seems to be evolving weekly. If ACTJRU come in then you get 3 pretty good games for each team over the October Long Weekend.
However, without them perhaps the President's XV (President's plural) should have been beefed up with players from all three associations (combined States style) and made the legitimate 4th wheel to the weekend.
There's certainly a few lads from 16's CHS (15 & 5) & CCC (Grasby, Sailor, Abdullah) along with a couple of others from the schools & Country trials who could be added to the Pres XV to really give the others a run for their money and a good hit out.
The first year is always the most confusing in building a tournament. However, as a vehicle for the three associations the above is becoming clearer in regards to how this weekend may look in years to come.
It's back to the future (really) as many, many years ago I played in a three way selection trial with Country, SJRU, & ACT in the U17 to pick a team to play the incoming NZ U17 team and the ARU U16's were always a selection trial for the Australian U16's. Once 2014 has been run & won we will know more about what future years may look like and be able to grow towards.
However, Chuck in a touring NZ & PI team (on the October Long weekend) and your up to 6 teams & the making of a quality weekend.
