Company policy is 1000 hours command and 500 hours ME TT before a twin, single pilot operation seat.

Not trying to be a smart-arse but I find it quite fascinating when comparing the hours required in 2013 before getting a single pilot twin command. And in the 1950's where an RAF pilot would be flying a four engine bomber single pilot with total of 500 hours or less.
Maybe the high experience level demanded of Australian GA pilots to get his first twin job, reflects the fact there is and always has been, a hopeless over-supply of CPL's and so the operator can cull any applicants that fail to meet the required hours. In other words it is not necessarily the skill or good attitude as a pilot that gets you that first twin job, but more like its a lottery biased towards hours attained.
