Thank you for your question. There are many ways that individuals can get involved in the law-making process. You can contact your local representative in the level of government responsible for a particular law. At the federal level, that means contacting the member who represents your electorate or one of the senators for your state.
If a citizen believes that a federal law is unconstitutional or has not been validly made, they may challenge it in the High Court of Australia.
