How did Australians get to America?

The first Europeans to arrive in Australia for permanent settlement were the convicts who were transported from England to Australia. They were fully cared for and were not left to fend for themselves. They were sheltered and fed, but made to work hard. If they shirked their duties, they could be flogged or have their rations reduced. The marines and officers who watched over the convicts had enough rations and livestock to keep going until farms could be established.

Hunting was carried out to a small degree. Europeans did not initially develop a taste for native Australian wildlife, and the colony almost starved until it had its first successful barley crop, and the 3rd Fleet arrived.
