Having the top section as a round robin makes sense, as there are very few round robin events held in Australia, junior or otherwise. The downside of this (although I personally don't think it is much of one) is that some players might miss out on either qualifying through strength, or not get invited, due to tournament considerations. If I remember correctly there was a bit of a blow up a couple of years back, when one prominent player did not get invited, resulting in vigorous discussion on various Australian chess forums.
The tournament began today, and results are available from the tournament website. You can watch the games from the top section live, although I have yet to find games from the other tournaments. However I was able to get a copy of the round 1 clash between the top 2 seeds, which I can show you here.
