Fred,
I am a bit confused on what you want the Kiwi's etc support on?
I am sure if you are helping CMAS to organise a European Champs at the same time as the World Champs in Durban that no one from the Southern Hemisphere will support you. If you are looking at developing a proposal that brings the UWH commission and CMAS back together to work in an honest and open way I am sure people would consider supporting you.
If there is an actual and definite split between CMAS and WAA then like all countries the SH countries will have to choose and seeing the WAA president runs the Underwater commission in Australia I am sure Australia will go with WAA.
