Oh look another Australian. Hi Charlotte and welcome!
As my good friend Sheep said, it's quite easy to make new friends here given the huge memberbase and the general diversity of the forum in general. It's always nice staying active and posting around, because you'll make friends easier that way. Someone might even share something in common with you!
Sheep already suggested the Video Games board for all the gaming interests, but we have a ton of Pokemon sections as well to talk about your Pokemon interests side. I've been a long-time fan myself, and I've been playing the games since 2003. Currently playing X right now and oh man it's awesome, Kalos is such a beautiful region.
Anyways, looking forward to seeing you around and yeah feel free to leave me a message anytime!
