Since we don't have a Political Geography/Demographics child board on the Internation General Discussion board, I have decided to pop this here to go with all the US redistricting information.
Australia regularly determines the number of electorates (equivalent of your Congressional Districts) each state is entitled to between elections.
At the current redistribution, New South Wales will be losing a seat and Queensland will be gaining a seat. The details are all located here:
