Q3. Bob Cowper, a triple hundred in Australia.
Q4. Gordon Rorke.
Completely correct on both accounts.
Bob Cowper, until recently when Matt Hayden scored 380, was the only Australian to score a triple century in Australia. He retired from cricket with very respectable batting and bowling figures, instead moving into a lucrative business career in Morroco which as far as I know he is still involved in at the age of 63.
Gordon Rorke was an exciting fast man from NSW who burst onto the Test scene just 12 months or so after his debut for NSW in 1957/58. The exponent of an unusual action which meant a lengthy drag during his bowling stride, he also came under criticism for the legality of his bowling arm during delivery - he was never called for chucking though.
He caught hepatitus early in his career and upon his return was never able to recapture the form that saw him play four tests for Australia.
He finished his career with the respectable figures of 10 wickets, at an average of 20.30 including 3/23. His first class figures included 88 wickets at 24, highlighting that it was no fluke he played Test cricket.
Had illness not disrupted his career he may have become a permanent fixture in the Australian side, given he made his Test debut at the age of 20 or 21.
