Why would you take a very funny tv show that is made in Australia and remake it with US actors? I really can't think of anything more disrespectful, it's not like they're speaking a different language, it's English. No doubt it will be word for word the same as the Australian version just with different actors poorly portraying the Aussie style of humour.
There have been numerious shows that have tried this and failed miserably (UK ones as well). The only show that has managed to do this successfully is The Office, and that only came into it's own when it stopped copying the english series and went its own way. Why can't the US just show the original Australian version????
