I'm Malaysian but I've been living in Melbourne since 2010, so almost 6 years! I'm currently working on my manga-styled comic.
There's not much of a comic culture I think. However, I did notice an increase in comic creators during Supanova this year, which got me really excited. It was so cool to see them showcase and talk about their work. I'm thinking of exhibiting my art/comics in a convention one of these days, so I really hope the comic scene grows!
I heard of a place called Squishface Studio in Melbourne. It appears to be a small studio where comic artists can gather to discuss and draw. It also hosts occasional lessons. Don't know how it's like, but it definitely seems like a great place to be.
