Lexus of Macarthur is located on an 8,000m2 site in Gregory Hills, in the Camden local government area, and commenced business in early 2016.

Greater western Sydney is an area of significant economic and population growth. There are 240,000 businesses in the region and its economy generates more than $80 billion in economic output per year, making it the third-largest economy in Australia behind Sydney CBD and Melbourne.

Its population growth has exceeded that of both Sydney and NSW over the past nine years and is expected to surpass 2.3 million by the year 2026.

Lexus Australia chief executive Sean Hanley said the establishment of Lexus of Macarthur came at a time of both substantial growth for the area and for the Lexus brand.

"The luxury market has expanded significantly in recent times, particularly from new-to-luxury customers," Mr Hanley said.

"The developing greater western Sydney region through Lexus of Macarthur provides us another opportunity to capture that growth. Our brand is fully committed to servicing this area and becoming a part of the community.

"This means providing customers in greater western Sydney with Lexus' renowned customer service, after-sales support and the full line-up of Lexus vehicles, including the dynamic new RC coupe and NX crossover SUV."

Lexus has appointed industry veteran Mario Kordovolos as Lexus of Macarthur dealer principal.

Mr Kordovolos, whose Clintons automotive business has serviced the Macarthur region for more than 50 years, said there was a significant opportunity for the Japanese luxury marque in the area.

"This is one of the fastest growing and developing areas of Australia and we see huge potential for Lexus to attract and retain a new set of buyers," Mr Kordovolos said.

"Our team looks forward to being part of the expansion and demonstrating to the growing population of Macarthur the many benefits of Lexus ownership."

Lexus of Macarthur will be accessible via an intersection on Camden Valley Way, a major arterial road that links the Hume Highway, M7, M5 freeways and interchange at Prestons in Sydney's south west.
