I used Unique pest and building (0413 529 097) for a unit I almost bought in Woodridge. Mick or Michael (I can't remember the name) was fantastic. He provided digitial pics of the unit (because I'm based in Canberra and was purchasing site unseen) and was extremely thorough with the check. He came accross some termites out the back and some other issues within the unit that informed my decision not to buy. He was reasonably priced to - $380 for building and pest inspection.
