It's going to be interesting. Things have definitely changed over the years. In the early days the home brewer was a big part of the show and I suspect that in those early days (about ten years ago) most people on the committee were home brewers. Last I heard, of the approx. 11 committee members, only one is a home brewer with the remainder being mainly commercial craft brewers. I did look into it heavily a year or so ago but the 450,000 hours per year I have spare, I need to spend here
The one thing we do know about the Royal Perth Beer Show is that we all get to gather and have fun. For you, I and many others, the judging results are unimportant. Unless thus year is different, we know that we'll never get the comprehensive judging notes we received in the early days.
Anyway, I dropped your beers off as well as @sinkas and mine. All the labels looked the same so to make things clearer, I wrote in black permanent marker, on my labels, "This is the Best Beer of Show." This will save the judges wasting time on the obvious. On yours I wrote, "Would have been Best Beer of Show but he forgot the mosaic." On sinka's I wrote, "Best Beer of Show if you like mulberries."
On a serious note, that was a pretty amazing difference on the naturally carbonated beers versus the forced carbed
