Just so you know, that’s an article debunking a bunch of myths about Grinnell College, a small liberal arts college in Iowa.

D’oh! :smack:
That is actually a link someone else provided in the “Can cows walk down stairs” thread. One of the drawbacks to tabbed browsing.
Tasman’s journal available here.
Australian natives never ventured into the oceans, being strictly coastal water sailors at best. That might be best demonstrated by the fact that Tasmania was isolated by rising sea levels for over 10, 000 years despite no more than 50 kilometres of open water separating it from the mainland.
Polynesians OTOH were the world’s greatest mariners for over 10, 000 years and made frequent and regular oceanic voyages of exploration and colonisation.
That is true of some Australian boats, primarily in the south. However in the North the technology existed to build more substantial log craft and these were used to reach Islands as much as 30km offshore.
Depends entirely on what you mean by “distinctive types of people”. All the people of NZ and nearby islands spoke dialects of the same language and all were mutually intelligible to one another and to people of Tonga. By linguistic and genetic standards all of NZ was populated by one type of people: Polynesians.
OTOH there were numerous chiefdoms and clans with varying lifestyles. The mainland North Island held the largest chiefdoms and small kingdoms with fortified towns and sedentary agriculture. As the climate became progressively colder agriculture became less viable and towns became smaller. The Chatham Islands and southern tip of the south island were populated by hunter-gatherer groups with no agriculture.
All told the people of NZ were far less distinctive than the peoples Western Europe in terms of language but far more distinctive in terms of lifestyle.
I don’t know whether to be embarassed or flattered. I’ve re-invented the choclate kettle. 
There is scant evidence if they did. The adoption of Polynesian-style shell fishhooks by some people in southern Australia, the use of Maori style battle staves by some people in the NE. A handful of what might be borrowed words. None of the evidence for trans-Tasman contact is very convincing.
One of those enduring mysteries is why nobody settled northern Australia. It’s not just the Polynesians, who may never have found Australia, but Malays and various other groups were perfectly familiar with Australia for millennia, yet none colonised for some reason.
Various explanations have been put forwards, often linked to the unreliable climate in Northern Australia. But quite frankly no explanation is very convincing given the abundance of permanant rivers and the fact that agricultural towns existed in the same climatic zone less than 500 km offshore. I suspect it was a combination of native aggression, poor initial colonisation sites, bad timing and malaria that killed any attempts. Basically just bad luck.
