The 2016 census results were recently released here and although metro populations will be done later (September IIRC), we're seeing all sorts of changes across the states.
Victoria had a revision in population estimate to reflect the census.. saw a record 146,000 to December 2016. (Generally 85-90% of Victoria's population is in Melb Metro).
In a post-mining boom/GFC world, we continue to hoover up loads and loads of population growth.
Good explainer:
Melbourne population growth blows the blinkin' doors off
Also density nerds, recommend Chris Loader on Charting Transport re: Melb changes.
How is Melbourne's population density changing? (2006-2016)
