I’ll add that most dialect speakers dislike their accent being mimicked, not just Australians; I know I resented the hell out of 1960s Greek comedies’ bad imitation of Cretan. If you don’t get it right, it does come across as mockery.
BUT for non-native speakers… we make a lot of allowances, because we know it’s not mockery. The accent will gradually come naturally anyway. And the less self-conscious you are about it, the more readily it will happen. We have met IRL, Miguel, and your accent is still mostly US/Philippines—but not completely!
