i need to name two laws for each level of government to do with childcare.
I can only help you with federal laws but each state parliament has a register of laws which you will be able to search and I suggest contacting your local council for information about their by-laws.
The place to look for existing federal laws is the Federal Register of Legislation. Government departments with responsibility for administering these laws also have information on their websites, for example the Australian Children's Education and Care Quality Authority.
You can also search for bills currently being debated by the Australian Parliament on the Australian Parliament House website.

Description
This diagram illustrates the three levels of government—the law-making bodies in Australia with three maps of Australia: Local councils (located around Australia in each local council division); State/territory parliaments (located in the capital cities of each of the 6 states and 2 territories); and federal Parliament (located in Canberra, the nation's capital).
