Yes, I can do it in Perth too! Of course, I used a packet mix (Donna Hay has a good one). I followed the instructions IGzactly, and got pretty good results. Not much worse than usual. Donna, the chocolate ganache needs a little more cream, and a longer standing time might help, but apart from that, nice work!
And for extra points, please admire the plate these treats are displayed on. It's hand painted by Jeff's mum Elaine!
