SPECIALIST vehicle manufacturer Byron Group unveiled its new plant in Smithfield last week.
NSW Premier Barry O'Farrell officially opened it, along with Byron Group chief executive Bill Pike.
Mr O'Farrell said western Sydney was an international leader in specialised manufacturing and the new cutting-edge factory enhanced that status.
"This is a great western Sydney success story and a huge vote of confidence in the manufacturing industry in NSW and Australia," Mr O'Farrell said.
"Byron Group's success and ongoing investment in western Sydney shows that despite recent setbacks, innovative manufacturing has a bright future in Australia."
The new factory employs about 320 people and produces emergency vehicles including ambulances and police mobile command vehicles for use across NSW, other Australian states and for export.
It will produce between 1500 and 2000 vehicles each year.
Mr Pike said there was "a future for manufacturing in Australia, but it's not in mass manufacturing".
"In the last few weeks there has been a lot of discussion about the automotive industry in Australia," he said. "We are a part of this industry and we have evolved into designers and manufacturers."
