I agree although I'm not Aussie.sorry my psychic powers are malfunctioning at the moment you are going to have to fill in a fair bit mor info here if you want a serious answer from anyone since without my psychic powers I have no way of know WTF you already have, how much money you have to spend or what it is you want to do with your gear
failing that buy 4 1Dx bosies and 2 of each every Canon L series lens 12 Ex600RT flashes
oh better get a couple of 5Dmk3 for backups and so you can do continuous RAW video with Magic lantern
that should about cover it
Other than this being exceptionally good advise, it's also what I miss after living overseas for 30 years, the Aussie sense of what most of us call, Humour, it doesn't quire translate in the rest of the world, but I still love it, I'm still laughing as I write this.
Also, very sound advice as always from WW
