In 1972, Whitlam withdrew troops from Vietnam. Whitlam's government during the post war period was able to establish diplomatic relations with communist countries such as North Korea and North Vietnam. His government was the first western government to recognise communist China and begun trade. This is because Whitlam and the Labour Party believed they should strive to work with their Asian neighbours rather than confront them.
He established new Commonwealth organisations to deal with Aboriginal and Environmental issues, ended conscription in the Vietnam War and provided free tertiary level education (University). The organisations were the Law Reform Commission, Aboriginal Land Rights Commission, Social Welfare Comission and an agency for concerning Women's Affairs.
He overlooked the passing of a Commonwealth Bill or legislation (I think thats what it is referred to, please clarify with other sources) called the "family law act of 1975" which led to the creation of the family court.
He set up the Australian National Parks and Wildlife Service and the Australian Heritage commission.
He also passed down many other legislations that include:
1. The "Prices Justification Act of 1973, commonwealth", which established a committee to overlook the prices of goods and services sold to consumers.
2. The "Racial Discrimination Act of 1975, commonwealth", which made it illegal to racial discriminate others. The law concerning racial discrimation had jurisdiction in the areas of employment, accessing public places, the ability to purchase a good or service from a place, renting property and etc.
3. The "Trade Practices Act of 1974, commonwealth", created copyright infringements, made restrictive trade practices illegal and made sure that consumers were protected from faulty products and misleading conducts by the seller or manufacturer.
4. The "Administrative Appeals Tribunal Act of 1975, commonwealth", was created so that it provided the ability to reflect the decisions made by government ministers.
He also devised the National Pipeline Authority to review the planning and construction of a natural gas pipeline system for the nation. He also implemented the Health Issurance Act of 1973, commonwealth legislature, to create a national and uniform health scheme referred to Medibank. This legislature offered free public hospital treament and a significant proportion of the cost for medical service paided by the government. As you mentioned in your first post. Sorry for the repetition, just wanted to reinforce it.
