Australia has higher life expectancy, lower mortality rates, and lower burden of disease compared to developing countries. Life expectancy in Australia is 79 years for males and 84 years for females, while in Africa it is only 50 years for males and 52 years for females. Mortality rates for children under 5 years old (under-5 mortality rate) and infants (infant mortality rate) are much lower in Australia at 6 and 5 per 1,000 live births respectively, compared to over 250 for under-5 mortality in Sierra Leone. Leading causes of death in developing countries include communicable diseases, malaria, and HIV/AIDS, while non-communicable diseases dominate in Australia. Maternal mortality is also much higher in developing countries
