Best Aussie YouTube channels?

I am looking for some new general interest YouTube channels to add to my regular viewing and want more Aussie content.

I like informative while entertaining content, but a lot of the what's out there is very US centric.

Topics such as Law, History, Science, Music Pop culture, and some Politics are a good start point, however I'd avoid anything to niche unless you think it's amazing.

Edit: Thanks for all the suggestions. It's going to take me a long time to respond, let alone watch them all.
