It was quite something to recently see the extent of transport infrastructure, completed and under construction, along The Northern Rd on Sydney’s outskirts.

The works are taking the route into the 21st century for the ever increasing number of south west and western Sydney residents.

The upgrading of the 35 kilometre road between Narellan and South Penrith is a city shaping project which will encourage more housing estates and so ought be effective in placing downward pressure on housing prices.

Investing in safer and more reliable journeys, the Federal Government has committed $1.2 billion to The Northern Road Upgrade, with the NSW Government committing $400 million.

This upgrade is part of the Western Sydney Infrastructure Plan, a $3.6 billion program which will deliver 60 kilometres of major road infrastructure upgrades before the opening of the western Sydney airport at Badgerys Creek.

Last weekend saw the rapid demolition of the 40 year old bridge at Orchard Hills.

Some 6000 tonnes of concrete and steel was removed by the 60 workers who did the job in three days, rather than the alternative of up to 20 weeks of night closures.

The Northern Road upgrade will provide increased road capacity for expected future growth when complete in 2022.

There is a very strong link between infrastructure delivery and the increase in supply of dwellings, and then an improved economy from the ensuing population growth that makes its home in the Macarthur region at housing estates such as Oran Park. The population of Oran Park Town sits at around 7500, some nine years after the first subdivision. Just two kilometres away is the more established Harrington Park, which was the 800ha Fairfax family Poll Hereford farm until mid-1990s housing approvals that saw it attracting aspirational middle class home buyers.

There was a 2013 study by the now abandoned National Housing Supply Council that found investment in transport infrastructure can galvanise dwelling activity, although the infrastructure needs to be of sufficient scale to substantially boost an area’s linkages to major employment nodes.

And sometimes that’s not always in perfect unison in terms of delivery.

The study found the nexus between transport projects, housing intensification and job boosting appeared to be much stronger in Melbourne than Sydney.

But that was before the new North West Metro, and all the apartment blocks within walking distance of the new stations.

There have already been more than one million customer journeys on the impressive system which only opened three weeks ago.

It’s rightly been described as a game changing project by Premier Gladys Berejiklian, who is now overseeing extending the line from Chatswood, under the Harbour, through the CBD and onto Bankstown.


A recent CBRE report forecast $1.4 billion of suburban development would flow every year for the next decade because of the Sydney metro rail project, with just 15 per cent of these developments officially confirmed.

The backdrop is that Sydney needs around 36,000 new dwellings every year until 2036 based on population growth projections.

And we certainly need more projects to avert rising unemployment
