I've found the office's very comfortable. The set ups at the desks allow for some adjustments to suits an individual's physical needs. There are a several different office's located around Canberra (and the also some in the States). The facilities are also to a good standard. The dress code varies throughout the Department as different Sections have different dress codes. Usual business attire is the most standard (e.g. long black pants, collared shirt, no ties).
