The prosecutors are the subjects to exercise those prosecuting powers. Due to different history,cultural traditions,constitutional systems and judicial systems,each country stipulates the extensive or narrow prosecuting powers for their prosecution service. The system of occupational security of prosecutors is an important condition in promoting the prosecutors to perform their powers independently as well as realizing the judicial justice. In Australia,the main powers of the prosecutors are to prosecute criminal cases. However,prosecutors with different ranks may perform different prosecuting powers. As to the occupational security,the Australian prosecutors enjoy high salaries and good welfares,which is a common characteristic of the occupational security in main west countries in the world. Therefore,during the process of current procuratorial reform in China,on the basis of national conditions and traditional accustoms as well as obeying by the developing rules of judicial powers,we should reasonably allocate the prosecuting powers and improve the welfares for prosecutors properly in order to promote the excellentization and specialization of the team of prosecutors and enhance their professional sense of pride and honour.
