Production went to the trouble of showing his friendship blossom with a young straight guy (Blair) only to then make out hugging someone you nominated as they’re evicted was the greatest crime…Perhaps Australian society (the general public as well as tv producers) weren't yet ready or equipped to understand an openly gay man and his mannerisms on a prime time reality show.
So they saw a man gossiping and acting on his feelings, and processed it as "bitching" and "backstabbing".
I’m not sure if he lives in Melbourne now but I’ve seen Johnny multiple times in the CBD since he was on the show. Years apart.
