I was curious so I looked them up. Their wiki doesn’t have much info, but it did mention they grew up in Adelaide Australia. I looked up median home price there and you seem to be right, it’s one of the richest parts of the country.

Regardless, from a quick cursory glance it seems they’ve been making videos since they were 11 years old. It was through their popular YouTube channel that they made certain connections. They for example managed to be a part of the filming of the Babadook, another great Australian horror movie.

So while yes, their wealth certainly helped I think YouTube becoming a conduit into more “legitimate” video form is something that I think will likely happen more and more
