THE Parramatta Eels have been been hit with one of the most severe punishments ever handed out in Australian rugby league following an investigation into alleged salary cap breaches.

NRL chief executive Todd Greenberg said the integrity unit discovered the Eels have been involved in a "deliberate, co-ordinated and sustained" system of salary cap rorting since 2013.

The punishments include:

- THE loss of 12 competition points


- FIVE officials deregistered

- $1.25 MILLION fine

- PLAYERS forced to leave club

- STRIPPED of its 2016 Auckland Nines pre-season title

A statement from the NRL said the integrity unit has discovered several examples where the club made payments to players that were not reported correctly to NRL officials.

The investigation, which analysed more than 700,000 documents and sources of evidence, also found the Eels were guilty of: "Conspiring with club suppliers to inflate or issue fictitious invoices to raise cash that was then relayed to players".

The Daily Telegraph reported the Eels were found to have been more than $3 million over the salary cap in a recent season.

In a stunning development, Weeks said the investigation found Parramatta is $570,000 over the 2016 cap right now because of illegitimate third-party deals sourced outside salary cap rules.

The Eels will have to move players to rival clubs before they can be considered eligible to compete for competition points this season.

Star playmaker Corey Norman could be forced out of Parramatta because of the salary cap breach.

Norman's manager Paul Sutton has confirmed he fears his off-contract star could be in the firing line when the Eels decide which players they need to offload.

The club is in crisis. $250,000 of the $1.25 million fine will be returned to the club if it implements changes recommended from a Price Waterhouse Cooper governance review.

The club's executive staff and board of directors have been decimated by the NRL's punishment.

Chairman Steve Sharp, CEO John Boulos, Head of football Daniel Anderson, Deputy Chairman Tom Issa, and Director Peter Serrao have all been handed show-cause notices as to why their NRL registration should not be ripped up.

Greenberg said the game was forced to act after exposing the Eels' culture of salary cap cheating.

"We will need to take a stand on behalf of the fans, the club and the game," Greenberg said.

"This would be a tough outcome for many people, particularly the players and fans, but we believe it would be the start of a process to make the Parramatta club the powerhouse it should be.

"Unfortunately, we may have to go through this pain for the long term health of the club and the game."

He said Parramatta has been fined for breaches of the salary cap in five of the past six years.

"As the governing body, we have a responsibility to act in the interests of the game for the long term," he said.

"At times, it gives us no pleasure to have to do so and this is one of those. But we have to take a stand on behalf of the fans, the club and the game."

Greenberg visited Eels headquarters on Tuesday morning to address Parramatta players and staff to inform them of the league's staunch punishment.

It comes after an NRL integrity unit forensic investigation, which into allegations of widespread salary cap breaches and third-party sponsorship agreements sourced outside salary cap rules.

Third-party agreements must be on an arm's length basis to ensure they do not become a way for NRL clubs to use sponsors to undermine the salary cap.

The reported punishment is the heaviest the NRL has handed out since the Melbourne Storm was sensationally stripped of two NRL premierships following an investigation in 2010.

The points deduction makes the Eels the fourth team in the history of the NRL to have points deducted for rorting, following on from Canterbury in 2002, the Warriors in 2006 and Melbourne in 2010.

Parramatta is still in a position to play finals football this season.

Club legend Peter Sterling attempted to find a positive in the disaster, arguing the Eels could still make the finals this season.

"If they won 12 of the remaining 15 games that would be close to the mark that would get them in," Sterling told Today.

"That's the ray of sunshine this morning on what's been a dark day and a dark couple of months."

He said this weekend's representative round also gave the club an opportunity to take stock of its situation and regroup.
