I think extraversion and confidence is generally preferred in Australia, like in job adverts they always want "team players, a people-person with good communication and leadership skills blahblahblah", although apparently back in the 70s more introverted, task-oriented people were preferred. This bias really frustrates me, it's not entirely our fault we're socially underdeveloped, some people just write you off bc you're shy and won't give you a chance...
Aussies also have a rep for being pretty friendly, laid back, not so serious people so you can feel a bit out of place being so anxious and reserved.
