Why does each Australian state and territory have different amounts of members in the house representatives?

Each Australian state and territory has a different number of members in the House of Representatives based on its population size. The Australian Electoral Commission (AEC) determines the number of members each state and territory is entitled to based on the latest census data.

Following the 2022 Census, the AEC redistributed the number of seats in the House of Representatives, effective from the next election. The following is the current allocation of seats:

- New South Wales: 47 seats

- Victoria: 38 seats

- Queensland: 30 seats

- Western Australia: 15 seats

- South Australia: 11 seats

- Tasmania: 5 seats

- Australian Capital Territory: 3 seats

- Northern Territory: 2 seats

It's worth noting that the House of Representatives is the lower house of the Australian Parliament and is responsible for representing the interests of the people. The number of members in the House of Representatives may change in the future based on population shifts and changes in electoral boundaries.
