For Aussie news you want !australia@aussie.zone, !australianpolitics@aussie.zone, and !news@aussie.zone.

For world news, there's !worldnews@aussie.zone for a community based on world news from an explicitly Australian perspective. There's also !world@quokk.au and !world@lemmy.world.

For true crime, it looks like !truecrime@lemmy.dbzer0.com and !truecrime@lemmy.world both exist but are not super active, so you may need to initiate the conversation there a bit more than you would be used to from Reddit.

!hiphopheads@sopuli.xyz is relatively active, and so is !metal@lemmy.world. There are also a few dedicated to subgenres of metal that you can find by doing a "Community" search for "metal".

There are a few TV and movie–related Communities, like !movies@lemmy.world, !movies@piefed.social, and !television@piefed.social. A few other specific franchises/shows have their own Communities as well.
