Body Corporate Duty of Care?

I live in a high-rise unit of which is classified as a “secure” building.  This means key card access upon entry to the building, the car park, each level of the building and to use the lift.  There is also multiple CCTV cameras on each entry and exit point in the building and car park as well as a security guard.  I have requested (as so have the police) the footage from these cameras as well as the log of the security guard and building access logs.  So far – I am yet to receive any information from the building manager.  Does anyone out there know what the duty of care of a Body Corporate is?  If they advertise a secure building – what actually are their rights and responsibilities.  Any help around this matter would be greatly appreciated – as so far they have been very un-cooperative with the process.

Thanks again for all the help – and email me (lmbasell@gmail.com) with any help around this issue or if you see any cheap Cannondale TT bikes for sale…
