Monaro Coaches stable several of its coaches outside the former Canberra Freight Terminal at the Railway Station; there is a fairly crude and temporary looking structure that provides cover for at least two coaches. Don't know if they're using any part of the Freight Terminal itself.
Last I Checked, the Canberra Trackfast Centre was meshed over. There is a section fenced off near the robbo's entrance, and the Monaro Coaches coaches were parked under that cover but not fenced off.
