Convict feels like something a Cricket fan would say, bald headed, sunburnt and wearing a horrific pair of shorts. The whitewashing of Australia is quite surreal even in this day of age, thousands of years of culture in Australia and people's minds swing straight to convict. Even away from the whitewashing, the convicts were essentially used for slave labour and whilst some would have been serious criminals, I'd bet a lot were arrested on petty stuff to provide supply for the labour demand the expansion of Australia required.
On a side note I went to an old prison settlement on Sydney Harbour and the conditions they lived in were genuinely horrific
