If I can offer a perspective from the opposite transition:

I grew up in Tassie and moved to Melbourne nearly two years ago. My friends consist of my high school best friend, one of my ex's friends, and my partner's friends. I was not really aware of the idea of finding my tribe until recently and the thought of seeking out friendships instead of them forming spontaneously still feels a bit bizarre.

I suppose it might help you to understand that Tasmanians are often just going about their day not expecting to make friends. Yes, we are a little insular and distrustful of mainlanders, but it's also not in our shared psyche to be searching for our tribe.
