Right now Australias population pyramid looks to be the slow growth pyramid. Australia has a lot of old people but it has lots of middle aged and young people. This means that the middle aged people will support the old people and the young will grow older get a job and support there parents. Because there arent as many middle aged people as there are old then when the middle aged get old there wont be as many of them and will be easy to susstain for the younger generation that is just now getting jobs and having kids of there own. All of thhis means that australia has a slow growing population that will be able to sustain itself for many years to come.
