Central Queensland will suffer another 100 job losses as Hastings Deering continues to downsize its mining services division.
It is expected 25 of the jobs will be cut from the Mackay workshops, and 50 in Blackwater.
A spokesman for Hastings Deering said the company would attempt to redeploy affected workers.
"Hastings Deering has completed a review of its Queensland operations and has commenced employee consultation to determine the right course of action to achieve operational efficiencies," he said.
"As part of this review, we are making changes to our mining support division which will see a reduction in roles across our Central Queensland operations.
"We have been working closely with impacted employees to identify potential redeployment opportunities and assist with their transition.
"The decision to reduce workforce numbers has not been taken lightly and we acknowledge the impact that these changes have on employees, their families and the communities in which they live."
Hastings Deering has cut its Queensland workforce by around 800 workers since 2013, including 100 workers, as was announced in May this year.
