Thanks Fran, that's a very interesting article giving good insights on Wirrpanda's background.
As for the lack of answer so far, it may well be due to realities in the field. The Foundation may not have much staff (only a manager for Perth and one for Pilbarra are mentioned on the website, in addition to 3 Role Models, one of who being David, who probably don't spend much time, if any, on admin duties). The staff/volunteers are probably so busy with the daily running of things that letters/messages of seemingly non urgent nature tend to be put on the side... then go astray and get forgotten.
If one of our Aussie friends found an opportunity to give them a phone call, they might stand a better chance to get to know more about the Foundation.
