With almost one-third of the total national population (8 million residents in 2016–171), New South Wales is Australia's largest domestic market.
The state's resident population increased by 134,144 people in the year to 30 June 2017, or 1.7%. Overseas migration continues to play an important role in the state's population growth, as well as deepening the base of skills and languages.
Sydney is Australia's largest city, with the greater metropolitan area home to more than 5 million people as at June 2017, accounting for 64% of the New South Wales (NSW) population.
Together with Greater Sydney, Newcastle and Wollongong account for almost three-quarters of NSW's population2:
- Newcastle and Lake Macquarie region—65 kilometres to the north of Sydney, with 359,106 people
- Illawarra region—85 kilometres to the south of Sydney, with 293,494 people
