Rugby Australia chairman Cameron Clyne welcoming chief executive Raelene Castle to the job when her appointment was announced two years ago.

Former broadcasting leader David Leckie has launched a withering attack on Rugby Australia chief Raelene Castle, calling her a "complete disaster" who "doesn't know rugby."

Leckie, the former head of Channels Nine and Seven in Australia, has suggested that Castle, a New Zealander who ran Netball New Zealand Netball and then Canterbury Bulldogs rugby league club before heading Rugby Australia, should follow chairman Cameron Clyne out the door "before she does any more damage", he told The Australian.

His attack comes just a day after Castle announced another Kiwi, Dave Rennie, would be the Wallabies coach through to the 2023 Rugby World Cup.

GETTY IMAGES Rugby Australia chief executive Raelene Castle has revealed her organisation began talking to Dave Rennie six months ago.

Clyne announced earlier this week he would not seek re-election when his current tenure expires in March.

"Clyne has fallen on his sword – and rightly so – but he should be gone tomorrow, not hanging around for the next few months and having any involvement in any decisions moving forward," Leckie told The Australian.

"We have to get rid of the entire board and start again. There's not a single person on it who deserves to remain there.

"Raelene has been a total disaster. She doesn't know rugby, she doesn't know Australia and, judging by her time at Canterbury (Bulldogs), she doesn't know how to manage a salary cap.

"She buggered that club. Central to your role when you're the general manager of a club, is salary cap. That's your first, first and first priority," Leckie told The Australian.

Leckie said Aussie Rules body the AFL were winning over parents by establishing training programmes in private schools in Sydney and Brisbane.

He said former Wallaby and now television rugby commentator Phil Kearns should be on the board of Rugby Australia.

Clyne admitted this week the "painful" decision to remove the Western Force from Super Rugby and the modest results from the Wallabies had blighted his tenure.

He and Castle have also had to deal with Israel Folau's controversial social media posts. Folau was sacked and since taken legal action taken against his former employer.
