I am advised:

There does not exist a comprehensive data set covering the aggregate length of all separated and shared cycleways that exist across NSW as a significant proportion of cycleways exist on local roads which are maintained by the relevant local council not Transport for NSW. As at August 2019, there were over 3,900 kilometres of known shared and separated cycleways in NSW. This does not represent anywhere near the entire length of all cycleways.

The NSW Government recognises that more people than ever before are walking or cycling to work or for leisure and fitness. Thanks to the strong economic management of the NSW Government, nearly $600 million will be invested into walking and cycling infrastructure over the next four years to support the growth in walking and cycling. This will bring the NSW Government's total investment to around $1 billion, the largest commitment in the State's history.

The NSW Government is committed to continuing to encourage people to walk and cycle as part of their everyday commute. We recognise that not only does it help relieve pressure on our roads and public transport system, but walking and cycling are healthy, active ways to travel. By continuing to invest in the construction of new separated paths and infrastructure, we help keep people safe while encouraging more people to take up these modes of travel.

The NSW Government is focused on cycling projects in line with Future Transport 2056 strategy. The strategy identifies the government's 40-year vision for transport planning to meet the demands of the predicted population growth in NSW. The strategy prioritises the delivery of connected cycling networks within 10 kilometres of metropolitan city centres by 2026, and within five kilometres of strategic centres by 2036. This vision supports the Greater Sydney Commission's objective of achieving a 30-minute city, where people live within 30 minutes of their workplace or services via active or public transport.
