Do not be lured into the fact that a Secure Complexes, Community Complex, or a Gated Communities are sure, in fact in most cased it is more likely that the complex will robbed before a general house. Most people will be lured into a false sense of security, and keep their units/houses unlocked in the complex, which is an easy target for would be robbers, thieves, and various other criminals.
While servicing many complexes around Brisbane, Gold Coast & Sydney, we find these are amungst the hardest hit compared to residential houses, even complexes with static or roming guards, they are still highly targeted.
Our best recommendation is ALWAYS keep your property locked, including cars, and houses. Have security cameras installed, both on the complex and on your own house, Sensor lighting to turn on in the event of sensing some movement.
Prevention is better than a cure, if you are able to stop or deter the would be robber from even approaching your house, is the best kind of security.
