Mosman has only increased its housing supply by 6% this century, but continues to baulk at state housing plan

Mosman Council will continue to push for its own custom-made housing plan, making it clear during a recent council meeting it does not not support the state government's plan to increase housing in the area.

What happened: Since late 2025, Mosman Council has been drafting its own in-house housing plan to supersede the state option it regards as unsuitable. 

Published in May, the council’s plan promises the same amount of housing — approximately 4,700 dwellings — but on terms the council can live with. 

• While the state plan spread development across the LGA, council plans confined development to a smaller area around Spit Junction and Military Road. 

At a meeting last Tuesday, council voted to endorse the plan following community feedback.

Artist’s impressions of what Mosman might look like under this masterplan are provided, though extensive use of AI imagery is apparent: locals may note that Spit Road and Military Road have been transformed into “Eleais Oeo Wby” and “Telengo One”.

The bigger picture: According to the most recent census data (2021), since the turn of the century, Mosman has built around 749 new homes, roughly a 6 percent increase. 4,700 new homes would represent a 35 percent increase.

To put that into context, since 2001 Willoughby has built over 6,500, representing a 26 percent increase, while Parramatta has built over 51,000 homes, representing an increase of 94 percent. 

Ku-ring-gai: 10,312 new homes, 29 percent increase 

Burwood: 4,754 new homes, 41 percent increase 

North Sydney: 6,712 new homes, 20 percent increase

Hunter’s Hill: 626 new homes, 13 percent increase 

Mosman: 749 new homes, 6 percent increase 

Still not happy: While having now drafted their own plan to increase local housing supply, the council still isn’t happy the goal has been forced on them in the first place. At the same meeting, they called on the state government to reduce their dwelling target of approximately 4,700.

Any answers: The Lorikeet asked Mosman mayor Ann Marie Kimber for the specific amount of houses the council would like the state’s figure reduced by. Kimber said the council did not have a specific figure, but that it would be “something the planning team is evaluating”. 

Direct action? Councillor Roy Bendall was particularly unenthused about the increase to housing. At the Tuesday meeting, he floated the idea of residents blockading the Spit Bridge as a protest. 

“We would have national TV coverage, and it would show that this area is serious,” he said.
