Sydney’s population hit 5.13 million at June 2017, an increase of 101,600 people (2%) since June 2016.
Net overseas migration was the major contributor to Sydney’s population growth, adding 84,700 people in 2016-17.
Sydney’s population boom would have been even greater if not for a net internal migration loss of 18,100 people. Sydney lost most people to other parts of NSW (40,000 people) and Melbourne (14,400).
Most of Sydney’s growth in 2016-17 occurred in the outer suburbs and around the city centre.
Cobbitty – Leppington, in the outer south-west, had the largest and fastest growth in the state, increasing by 4,100 people (22%), ahead of Riverstone – Marsden Park, which grew by 3,800 people (21%). Net internal migration was the main driver of growth for both of these areas in 2016-17, contributing to 90% and 87% of population change respectively.
The inner-city area of Waterloo – Beaconsfield had the next largest growth in 2016-17, increasing by 2,600 people (7.4%). Around 68%t of this growth was due to net overseas migration.
