Its says the redundancy program will cost $13 million.
“This is in addition to the 375 position which were made redundant earlier this year in our NSW/ACT operations at cost of $8 million,” the statement said.
“Westrac has implemented a series of efficiency and productivity initiatives over the past 12 months in an effort to streamline its cost base, but these measures along have not been sufficient in view of continuing challenging market conditions.”
The company says it will be left with a workforce of about 3,350 in Western Australia, New South Wales and the ACT after the restructure.

It is a subsidiary from Seven Group Holdings, which also operates the Seven Network.
