Tom Moody has put his decision not to seek re-appointment as Western Australia coach down to an expected growing role in the IPL.

He said the decision was not because of the Warriors' disappointing results over the past two summers.

The Warriors made just one final in Moody's three years in charge, the 2008 KFC Twenty20 Big Bash final loss to Victoria, and again this season the results have been disappointing in the Big Bash, Ford Ranger Cup and Sheffield Shield.

Moody returned to his native Perth as WA coach on a three-year contract after guiding Sri Lanka to the 2007 World Cup final following a decorated playing career that included eight Tests and 76 one-day internationals for Australia, along with leading WA to two Shield wins.

He was unable to bring that success to the Warriors as coach, though, meaning WA have not won a one-day title since 2003/04 or a Sheffield Shield since 1998/99.

According to the coach, that had nothing to do with his decision to move away from the WACA after the last two Sheffield Shield games against Victoria and Queensland.

Instead, he cites his role with IPL franchise Punjab Kings XI and work with Vikas Rambal of Perdaman Industries as the main factors.

"My reasons are really that the cricketing landscape is growing rapidly and my connections in India is a role that potentially is going to be expanding, and my role with Vikas Rambal and Perdaman Industries is another commitment that will expand going forward," Moody said.

"I had to consider my options and what I could fit into 12 months of the year, and what I couldn't.

"I've given everything I possibly could over the three-year period to the WACA and the team, and unfortunately I've had to sacrifice my role here to move forward."

Moody made the decision now given Queensland's Sheffield Shield win over Victoria means the Warriors have no chance of qualifying for the final.

But he said it was the decision he was going to come to no matter what happened.

"Since we are out of contention, I thought it was important that the WACA had as much time as possible to find the right candidate to take this group forward next season and beyond," Moody said.

"Regardless of whether we won the Ford Ranger Cup or KFC Big Bash or qualified for the Champions League, I don't think my decision would have changed. With the position I'm in at the moment with the opportunities and challenges that I face going forward, I had to make a decision on this role."

Moody will head to India to coach the Punjab franchise once the Shield season is over and while at the moment it is only a part-time gig, he expects it to only continue to grow.

"The interesting decision I had to make was the diversity that the IPL offers. At the moment, we are only seeing one tournament a year, but going forward there's no doubt that will change and as a coach I need to be available to make sure they have a coach that is full time," he said.

"That's to not only be available throughout tournament time, but during the preparation stages, talent ID camps that go on throughout and the various exhibition or overseas matches that might take place going forward."

As for his replacement, WACA chief executive Graeme Wood wouldn't be drawn on discussing potential candidates, but former South African coach Mickey Arthur has expressed an interest and would be right at the top of the list although the WACA will go through a thorough process first.
