In both countries the areas of the electoral districts vary according to population density. Electoral districts in more densely populated (metropolitan) areas are smaller than in less densely polulated rural or isolated regions.

This process in known as electoral redistribution. Members of the Australian House of Representatives serve a 3 year term whereas US members of the House serve for 2 years.
