Ash, Male, 30

Hi I am a single, clean, quiet, working Australian male. I work M-F around 8-4.
I'm looking for peace, quiet and privacy. I don't want to hear others, neighbours, planes, traffic or barking dogs from my bedroom. In a nice suburb (not Western Sydney)
The room needs to be large (3x3m at least) to fit queen bed, desk, TV unit and wardrobe if no BIR.
For housemates, 20s-40s is good. People I can play board games with and/or watch sci-fi tv/movies. People that have an interest in health & fitness ie regular exercising.
I only want to live with Australians/English people not other languages/cultures. I think 2-3 people is enough with at least 1 other male.
My budget of $320/w is including bills and internet
I will consider more areas than I have listed
Cat-friendly would be a bonus.
I have to give 2 weeks notice.
