was just lookin at the thq webpage now... http://www.thq.com.au/
they have archives of news going back to to 2001...but they have no phone number or street address..... did you get any more information from them about thier brisane studio? and when and if its allready opened? a 1800 number to call and a support email addy is all they are giving away....
Post an email to firstname.lastname@example.org for those details.. If you dont get a reply, let me know, and I might email someone from thq for you. Why do you want their number/address at the moment for anyway?
