According to Hofstede's cultural dimensions theory, the USA and Australia have very similar cultures, although 'mateship' is not a dimension considered I will admit. :D
I would suggest that all national cultures value loyal friendship and working as a team.
That said, 'mateship' has a sense of egalitarianism to it, and while Australia and the USA are egalitarian cultures, that is lacking in other nations, e.g., China.

"Sometimes he fought the constant pull of sleep, forcing himself to socialize when his mind was in a fog. But by denying his problem, he sometimes put himself — and others — in dangerous situations. One day he was cruising toward the mountains at 100 miles an hour on Red Bull, his large, cherry-colored motorcycle. One moment he was staring at the lush, green foothills ahead; next thing he knew, an older woman on a bike slowed down in front of him to make a U-turn. He tried his best to stop, but couldn’t, crashing into the back of her bike. They were both thrown to the ground. She was injured badly, bones visible on her shins and hands. Lloyd had only a few cuts and bruises, but he was rattled. How had that happened? he wondered. Did I zone out?" What an asshole.
