She warned there could be cuts at the Ballarat Mail Centre after Christmas, however, as new parcel technology is introduced in the West Sunshine facility.

"The current cuts (of 900) are to headquarters staff only. Jobs at the mail centre in Ballarat should be safe until after Christmas, but after that we're not sure."

Fairfax Media revealed on Saturday that 900 jobs, from a total workforce of 32,000, would be cut to save $90 million a year.

Ms Doyle said these cuts are an attempt to normalise reduced services.

"(The cuts details) was a leak from management, in a further effort to get permission from parliament to reduce delivery to three days a week."

"We reckon if there's any job going it should be the CEO (Ahmed Fahour). He's all over the place, talking about six-day-a-week delivery last week, then back to the three days. He should go back to the banking industry, because he's not suited to running a service with a small amount of profits."

In a statement, Australia Post said the cuts are necessary due to a changing industry.

"Australia Post has made it very clear that it is confronting dramatic change due to the impact of declining revenues in our letters service. Our Managing Director and CEO Ahmed Fahour has publicly stated that the losses in letters business have already overwhelmed the profits in parcels and without reform, the letters services will lose over $1 billion annually in a few years."

Australia Post last year reported a 14 percent increase in revenue, to $5.8 billion, and paid Mr Fahour $4.8 million in salary and bonuses.

Last year, Australia Post threatened to close regional sorting centres and move processing to Dandenong at the cost of 30 local jobs, but a local campaign and lobbying by Ballarat MP Catherine King has kept it open.

At the time, she said:

"Our postal employees work extremely hard, but they are increasingly being asked to do more with less. Ballarat deserves first class mail services."
