This is a great question. Thanks Rory. You have quite a few representatives in the Australian Parliament.
In the House of Representatives, you are represented by the member of parliament for your electorate. You can find out more about the member for your electorate, including how to contact them, on this list of all members of the House.
If you don’t know the name of your electorate, you can find this by searching for your suburb or postcode on the Australian Electoral Commission website.
In the Senate, there are 12 senators for each state and 2 senators each for the Australian Capital Territory and the Northern Territory. You can find out more about the senators that represent you, including how to contact them, on this list of all current senators.
