The Australian Sports Anti-Doping Authority's (ASADA) interim report into Essendon's supplements program may never be made public, according to Federal Sports Minister Don Farrell.

Under the Privacy Act and the National Anti-Doping Scheme, releasing the report is not authorised and as such, the contents of the investigation stand to remain undisclosed.

"I'm advised that ASADA is entitled to disclose information to a sporting administration body (such as the AFL) in connection with an investigation under clause 4.21 of the National Anti-Doping (NAD) Scheme," a spokesman for the minister told the Herald Sun.

"The AFL is covered by the Privacy Act 1988, so use and disclosure of information by the AFL is subject to the National Privacy Principles.

"I'm advised that there (is) nothing in either clause 4.21 of the NAD or in the NPPs that would authorise the report being made public."

The report suggests that while protected by the Privacy Act, it is possible that snippets of the report may be released provided they do not risk any individual's privacy.

The ASADA report, more than 400 pages long and referencing more than 13,000 supporting documents, was handed to the AFL last Friday. Essendon was given a copy this week and there is growing speculation the league will announce its findings on Monday or Tuesday.

Hird insists club should be allowed to play finals

Hird, who claims he has not seen the report but has been made aware of its findings, has defiantly reaffirmed his club's right to play in the finals.

"We're playing tomorrow, the next week, the next week and the next week, because we believe we've got a right to play in the finals," he told reporters outside a training session this morning.

"We believe that so we're not doing all this training we've been doing over the last six months, we're not going out to risk our players' bodies by playing every weekend for no reason.

"We believe we've got a right to be there."

The Bombers have been under ASADA and AFL investigation since February 5. Essendon could be stripped of their premiership points over last year's supplements program at the club.

Since the report's release, Essendon and the AFL have remained tight-lipped about its contents, though Andrew Demetriou has spoken in favour of making the findings public.

"We hold a view that it is very important that we get all the facts out there publicly, which includes aspects of the report that don't hinder privacy," he said.

Demetriou was also in favour of open hearings should any individuals be charged as a result of the report.

"If there is to be a charge laid, that will be a discussion between the various legal parties, taking into account privacy issues.

"But there is a lot of merit in a public hearing, absolutely."
