Qantas is yet to confirm how planned job cuts will affect hundreds of staff and which facilities will be hardest hit, the union representing the airline’s maintenance workers has said.

Australian Workers Union state secretary Cesar Melhem, said was still no confirmation from Qantas of where the long-foreshadowed axe will fall.

"Our members are extremely anxious about this - they are not in a good space," Mr Melhem said.

His comments follow reports in the Herald Sun this morning that the airline would sack about 400 workers from its Tullamarine heavy maintenance base and another 600 from Avalon, west of Melbourne.

The airline has confirmed the workers will be axed but a spokeswoman said it was uncertain which of the three bases - Avalon, Tullamarine and Brisbane - would shed the jobs. The decision will be made within weeks, she said.

"The significant reduction of maintenance required on our aircraft means we do not need three separate maintenance bases," she said.

"We are continuing to assess various options and expect to make a decision by mid-May."

Up to 1000 Qantas job losses were flagged as early as February. Victorian Premier Ted Baillieu met the airline and airport bosses in a bid to minimise the impact.

Mr Melhem said Qantas was expected to soon announce which Victorian maintenance centre would be affected, and said the airline should do so sooner rather than later.

Today's announcement also follows reports of a review conducted by the airline, which concluded that the division at Tullamarine could not be saved and must close within months, with another 660 workers at Avalon not expected to keep their jobs beyond two years.

It also found that Avalon, near Geelong, was not viable beyond two years without major state government investment, News Ltd reports.

The report says Tullamarine workers will be offered mining jobs in Western Australia during a careers information session at the hangar.

The sackings look set to continue a horror run of job losses in Victoria which include 350 jobs at Toyota, 50 workers sacked at rail operator Metro and, in March, Murray Goulburn Co-operative slashing 60 jobs by closing its milk powder drying operation.
