I haven't had a look at Wacol yet due to having to bail my trip but I will scout it out in February and will report back on here.
Wacol Mental Asylum is very close to the operational Prison so I do expect heavy guarding of and around its facilities and structures no matter what, I think that Wacol Mental Asylum might even be a potential risk to the Correctional Facility in a certain way that will require daily and nightly patrols. I still have my scouting trip planned in February so I can confirm more details. In the mean time, i gotta see if I can re-do my Brisbane URBEX All-nighter trip as last time it all went bottoms up.
The gaurds are in teh area to guard it cause the mental hospital is next to it and it's on there land so no extra cash flow to guard it but good luck in getting in.
