A bodyguard is a person who protects another person; a security guard protects property. In Australia this requires a separate licence (Government tax) for each State you operate in ... each has their own requirements (which are basically identical), to justify charging you a fee to try and earn a living in their State. We used to provide bodyguards, but found it noncompetitive; the demand to be either for unreasonable options (e.g. 2 hours whilst I go to court, or just for an hour while I go to the shops, or for people suffering delusions ... we cannot protect you from the imagined) or for people who increase the risk of the bodyguard, and are not interested in reducing the risk to themselves (remain in the house, when there is a risk of violence, when the logical answer is to leave). Many uniform security guards have obtained their bodyguard licence, and many returned servicemen (and women) from recent wars have the necessary experience and training, and have become licensed, which has increased supply.
Australia is a low risk environment, generally. There are high risk areas, and actions, including domestic violence threats, gang violence, religious groups and left wing, right wing extremists, which raise the threat against a particular person, but the general environment risk remains low. Protection of people against these threats often involves actions which go against the expected actions of a real bodyguard. Real bodyguard actions involve removing the client from the threat, not moving towards the risk. This is often what the client expects in the above scenario's. They have the 'movie' image of a bodyguard. Some believe they can start a fight, and have the bodyguard act as a 'thug' to finish it ... we were never that kind of a service. Use of force is the last line of defence, where avoidance isn't possible.
Possibly the worst of these tasks is the 'movie star' client, who expect the CPP operator to protect them, as they do the things that go against security, such as publicity for their attendance at major events, for some transmitting every minute of their lives, and for others seeing the security as a ball and chain they need to give the slip so they can party! ... this makes the bodyguards task much more difficult. One operator accurately described some clients in this class as being like a spoilt child with ADHD, and lots of money.
