Australia's print employers have joined the fight to get the country's postal service to reconsider its shrinking services and changing business model.

Under newly-appointed chief executive Jason Allen, Printing Industries has announced a national campaign this week to win political support for reform.

The moves follow a campaign headed by mailing house D&D Mailing and director David Docherty, who wrote to both communications minister Malcolm Turnbull and shadow minister Jason Clare. Objecting to ongoing increases in business and Print Post pricing, he urged Turnbull to consider what business Australia Post was in.

Now Printing Industries is on the job, following the appointment of Allen in mid-July and "the result of months of planning and research".

Allen says Post was showing a total disregard of its stakeholders and continued to ignore recommendations of a Senate inquiry into the performance, importance and role of Australia Post. "The price increase issues are a major concern and they are the tip of an iceberg threatening the future viability of the entire mailing industry and all the associated sectors whose economic livelihoods are under threat by Post's blindsiding tactics," he says.

"Post has consistently failed to consult and to make an economic and social business case substantiating its actions. It has failed to highlight any improvements and benefits that businesses would be expected to provide their clients with accompanying any price increase."

Printing Industries accuses Australiua Post of avoiding "quantifying the impacts of its actions" across the community and failing to provide economic and social evaluation in monetary terms of its proposed actions. "Printing Industries along with key industry stakeholders, has commissioned the research, done the homework and prepared the math that politicians around the country need to see to understand what has been going on and to expose the erroneous pathway that Post is on."

The employers' group will send politicians its report on the Economic Contribution of the Australian Mailing Industry and a plea to "pull this monopolistic, national service provider into line" and into compliance.

The mailing campaign to politicians will be followed by meetings with mailhouse representatives next week in Sydney and Melbourne as part of the "call to action" encouraging the industry lobby every politician to support the campaign. A significant submission will be prepared when the ACCC calls for feedback on the proposals.
