There is no universal or comprehensive system of compensating people who have suffered injury or disease in Western Australia. In each State and with in the Commonwealth legislation a range of compensation and sickness benefit systems is dealt with. An injured person must come within at least one of a number of the specific systems to obtain compensation. Some people are injured in circumstances which may entitle them to compensation from more than one 'system' of compensation. Other people will suffer similar injuries in circumstances which will not entitle them to compensation at all. The following chapter covers the most important 'systems' or circumstances which entitle injured people to be compensated for those injuries. Injuries arising from car accidents are dealt with in Chapter 6: Car ACCIDENTS, while medical negligence claims are addressed in Chapter 22: HEALTH CONSUMERS RIGHTS.
