NSW premier Gladys Berejiklian and Seven Group Holdings chairman Kerry Stokes have officially opened WesTrac's new Sydney headquarters in Casula.

The premier and Stokes was joined by members of the Seven Group Holdings Board, including CEO Ryan Stokes and WesTrac NSW/ACT chief executive Greg Graham, as well as WesTrac customers, local and state politicians and members of the media. 

WesTrac recently relocated its Sydney operating base from Holroyd to a 24,000sqm site at the Crossroads Logistics Centre in Casula. Situated at the intersection of the M5 and M7, the new facility is closer to a number of significant current and future infrastructure projects, as well as to the businesses of many WesTrac customers. 

"WesTrac has invested over $200 million since 2012 to support the growth in the NSW economy, and Casula is the latest in this series of investments right across the state," Graham said. 

"Casula complements our $170 million facility at Tomago, which opened in 2012 and was designed as a long-term commitment of service and support to the community of Newcastle. 

"This investment has been designed to support our customers, who play an integral part in the construction of infrastructure to support economic growth in NSW. 

"Our end customers are typically mining companies and construction/earthmoving contractors who work on large (usually government funding) infrastructure projects."

Graham says this investment is a reflection of the company's confidence in both the current activity levels and future outlook for the construction and resource sectors in NSW.

"We see a resurgent construction sector and improved commodity prices underpinning strong growth in the NSW economy for several years to come," Graham continues.

"We employ over 150 people at Casula, including 10 apprentices. The continued growth in activity in Western Sydney is creating more jobs for local people, and we expect that to continue to be the case.

"This facility will generate revenues of $200 million per annum in the Western Sydney economy and the opportunities for future employment growth are considerable." 

The new facility at 280 Beach Road Casula opened its doors for operation on July 16. It boasts a number of features aimed at enhancing the customer experience. The warehouse is 1500sqm larger and features new automation and inventory management systems.

Meanwhile, the drive-through parts bay caters for sectors including heavy construction, building construction, commercial engines, paving and highway trucks.

A report by forecasting consultancy Macromonitor earlier this year found investment in major infrastructure projects across the country is set to soar over the coming five years, with projects in Sydney and NSW making a hefty contribution.

WestConnex, the Sydney Metro City and South-West projects, Western Sydney road projects, and Sydney Light Rail are all expected to contribute to a national spend of $16 billion a year by 20202, with the figure much higher when smaller infrastructure projects are taken into account.
