Optus will cut 350 jobs from its workforce in the next four weeks in an effort to improve sustained profitability and increase efficiencies.

The company said it would consolidate roles in a number of corporate functions while some other positions would become redundant

“Optus must continually review its operations to ensure we remain sustainable and competitive in the years ahead,” the company said in a statement on Wednesday.

Australia’s second largest telco has already reduced staff numbers; over the nine months to December 31, 2013, it had an average of 8,685 employees, down from 9,130 in the same period a year earlier.

Those changes have recently delivered profit growth, with the company making a net profit of $722 million in the nine months to December 31, up from $480 million in the same period a year earlier.
