Nearly half a million Sydney workers commute each day to just four major job hubs - the central business district, North Sydney, Macquarie Park and Parramatta.

New Bureau of Statistics analysis of 2016 census data shows Sydney commuters travel an average of 16 kilometres from home to work.

The report also underscored Sydney’s status as Australia’s public transport leader with 27 per cent of the city’s workers taking a train, bus or ferry to work, way above the national average of 14 per cent.

Around 320,000 commuters descend each day on the Sydney-Haymarket-The Rocks statistical district, which takes in the CBD.
