I bet the population is still rising.But they do have ~1 million fewer than they did a couple of years ago, so there is that.
I really, really don't want to see Australia's population grow. I've seen Sydney more than double in my lifetime. Nothing about that has convinced me that more people, less infrastructure per capita and more crowed surrounds is any sort of nett benefit to human happiness. Quite the contrary IMO.
