While Essendon would probably disagree, Fahey reckons the Bombers have so far avoided the worst they could potentially expect in terms of investigations into their use of supplements from 2011 to 2012.
In a belligerent and full-blooded interview with the Australian Financial Review, Fahey labelled the AFL a 'sacred cow', questioned why WorkSafe Victoria has yet to look into Essendon and warned the supplements scandal will not go away.
"I expect there will be several charges by ASADA," Fahey said.
"It's only a matter of when."
Fahey took aim at the AFL's handling of the supplements scandal, claiming the league is only interested in fighting drugs as long as they can control the story.
"No sports minister or sports official I've met anywhere in the world wants to have their athletes in the headlines for the wrong reasons," the former NSW premier said.
"The first thing they say to you is 'how can we fix this?' They'll give you all the support you want and tell you why it's so important to fight drugs in sport as long as it's not their sport.
"When their sport gets caught with it, they want to make it go away. If they can cover it up, they will."
Fahey also slammed WorkSafe Victoria – the Victorian work safety authority – for ignoring the situation at Essendon so far.
"How can James Hird be at the helm of the club as the head coach when 4000-plus injections have been given to playing staff, none of which anybody can tell us what it was, most of which we know is not approved for human consumption, and put at risk these kids, and not have WorkSafe Victoria banging on their door that this is an unsafe workplace?" Fahey asked.
"Nothing's been done there – that's the sacred cow AFL is. It's disgraceful that WorkSafe haven't been in there tipping it on its head."
