PD is for all levels of government. Federal, state and local. This is important for representing minority groups.
Minority groups often live in particular geographical areas. They will likely be able to make small changes in the local area at a council level to make them feel more welcome.
For example, a Jewish community may be able to get an Eruv around their community, and a Muslim community a public prayer room in their local shopping area.
In addition, all Australians are protected by the Australian Constitution and common law. PD believes it will be helpful to get a human rights charter enshrined in the Australian Constitution for this model. In Federal and most state governments there are two houses of parliament. This means bills need to be voted on at least twice to become law, providing an additional layer of protection.
