I had the privileged of meeting Austin when he dropped a surprise visit to the 'Snake sit in' record attempt at Chameleon village... he is a completely different personality compared to his TV persona... very quiet and reserved, he hypes it for the camera but very friendly, and nice about talking to complete strangers who ask for a photograph
Brady Barr irritates me... he screams like a girl and is so obviously over the top that I often change channels if one of his docco's are on... and that's saying a lot! I'm a docco addict!
Mark O'Shea is at least gentle with the animals he shows, doesn't fling them around like some other presenters *cough* *Barr* *cough* not as exciting a presenter as Stevens... but still good in my opinion.
