Upper management at The Post discovered this week that more than 50 of its statewide bureau managers and staff members have been routinely exchanging hardcore pornographic emails and porn videos.
The scandal has rocked The Post's administrative backbone and resulted in numerous dismissals and resignations.
According to reports, some of the emails contained child porn.
Four of The Post's managers have resigned, two have been fired, and the rest have been suspended indefinitely while management investigates the hard drive content and email habits of every staff member belonging to the newspaper chain.
Some employees were reported as being only minimally involved, while others were in the habit of exchanging hundreds of porn emails over a certain period of time.
In retaliation, some workers have threatened to appeal their dismissals through the Australian Industrial Relations Commission.
Police investigations are also pending in the case of those workers who were distributing child porn content.
The entire porn racket unfurled when a news bureau manager accidentally sent an email containing porn to every staff member in his bureau.
The Post, which is the country's largest employer, retains a staff of around 36,000. Internet access is restricted to managers and administrative staff.
According to reports, the union representing Post workers has called for an independent inquiry into the porn scandal that has left five of its members without a job.
