Last time we used Sprinterboy on these Forums, or Justin as watermarked in these forums, he was great, not sure if he'd be interested again though. I think we started at 9:30pm or so and finished around 2am. Long night, but we went Ainslie first, then Phillip Medical Centre, and finally Rememberance place next to Questacon. I have some more pics as well, but I think people have already seen them, there is another thread detailing all this from about 18 months ago.
I'd be keen to do it again, depending on a time.
