I watched my first Australian Chase last night, the chaser was 'supernerd' who seemed to have quite good knowledge. I liked the fact the contestant didn't turn around to discuss the amounts offered with the team, like they do in the UK version and just said which offer they wanted.
I guess this is because Australian TV seems to have a lot of adverts, even compared to the UK so they cut out as much filler as possible, even the host (who I liked) didn't ask them about their personal lives as much as Bradley does.
