Here's a simple, friendly description you can use:
> Hi, I'm Andrew from Papua New Guinea. I'll be moving to Australia for work. I'm open, friendly, and easy to get along with. I enjoy cooking as a hobby, and I'm a casual drinker. I'm usually quiet and respectful of other people's space, but I do enjoy listening to some old music at a moderate volume now and then. I'm clean, responsible, and looking for a comfortable, respectful place to call home.
