if you're looking for something 'industrial/commercial' themed; the loading dock and underground parking at the rear of the Officeworks/Petbarn/BCF is available in Tuggeranong (adjacent to Bunnings).
There's a spotlight on after hours in the loading dock, and fluorescent lights in the car park (not sure if they're locked up after hours by security.. last time it wasn't).
Also, the whole parking complex of the Hyperdome is available too. If you can figure out the labyrinth to access particular parts and levels of the carpark - you've done well.
The DHS building (Caroline Chisholm Centre) in tuggeranong is pretty funky too.. I've yet to take photos there, but I think there are spotlights from the ground shining on to the building.. and possibly funky coloured lights on the building - not sure, i should know considering I work there.
