(Probably best to put this in the Newsroom forum.)
Pesch is still based in his native Australia AFAIK and does a lot of freelance and corporate work. He also runs his own production company (with his spouse as business partner) producing independent documentary programmes for some of the major outlets.
"Peschardt's People" and - latterly - "Peschardt's Business People" were two such productions commissioned by BBC Worldwide. (Mike anchors the programmes and his wife is involved in production).
