Just a coupla historical footnotes about the early days: Mother England sent a total of 162,000 convicts, both male and female, to Terra Australis through the period of The First Fleet of 1788 through 1868. There were a total population of about 1,000,000 'whites' living here at the end of the convict period of 'Transportation'. North America took in an unverified 50,000 'undesirables' prior to the American revolution. Therefore more Aussies are convict-related than in the US as a percentage of population and as a number. Convict heritage is often regarded in Australia in modern times to be a badge of pride. The vast majority of convicts sent over were English/Welsh at 70%, Irish 24% & Scots at 5%. Many people don't realise that the Poms (Brits) sent a large percentage of convicts of Canadian origin, Maoris from New Zealand, Chinese from Hong Kong and slaves from the Caribbean as well. South Australia and the Northern Territory of S.A. never accepted convicts directly from England, however, they accepted many ex-convicts from the other states after they'd been given limited freedom. Many convicts were then allowed to travel as far as New Zealand to make a fresh start after serving their term, but they were never allowed to return to Great Britain.
Modern Australia was built on the backs of these convicts. Many non-native and ultimately destructive animal and plant species were brought in to make the settlers 'feel more at home' too. Foxes, rabbits, cane toads, deer and camels, gorse & lantana, to name a few. Talk about introduced pests! That's not just you and me, white man. At the end of the day, Australia, to those who have not heard, is known as The Lucky Country. This is due to the fact of it being a modern, stable economy, a democracy with a high standard of living, literacy and birthrate, an overall good climate and a fairly relaxed lifestyle. Though I reckon American television/pop culture, and the availability of fast food might be spoiling some of us!
Now for the motorbike content of the discussion; Australia has some of the harshest, driest, hottest & wettest conditions on the planet, but with some amazing scenery and smaller, bendy two-lane motorbike-suited roads. All the better for those of you so inclined to travel here for an extended time, take a good long motorbike holiday, meet the locals, drink some beer, take in that scenery and the incredible flora and fauna, and while you're at it have a Dingo's brekkie (a good look around).
