Australian national myth-making dwells heavily on the evils of transportation. How the founding fathers and mothers of Australia Fair, all British and Irish prisoners, arrived in 1787 in the "First Fleet". They'd been dispatched by judges to distant shores to build their own jails. More than 160,000 were to follow over the next 80 to 90 years.
For the English government, it was a simple and cheap way of removing "criminals" from society without actually hanging them.
More than two centuries later, the inheritors of this continental-sized penal colony have decided to dip into the past and get rid of present-day miscreants in the old-fashioned way. Since a law change in November they've been targeting Kiwis and other foreigners, rounding them up and throwing them into detention facilities prior to transportation. These days, it's back to their places of birth. Even those who arrived as infants decades ago are dragged away from wives, husbands, children, siblings and parents.
The added twist to the present day model is that miscreants are forced to first do their time in an Australian jail, then get doubly punished by being tossed into an immigration facility for months on end, then deported.
The November law change was also retrospective. Immigration authorities are dredging through old convictions and if they add up to a year or more's jail, into a holding cell goes the victim. Even the 18th century gaolers were not that cruel.
