Australia batsman Mike Hussey says the tragic and mysterious death of Pakistan coach Bob Woolmer three days ago has had a big effect on him.

"We're pretty shocked by the news and it's quite saddening really," Hussey told reporters on Wednesday at a team training session in St Kitts.

"I've had a bit of a hollow feeling in my stomach for the last few days.

"We have a great respect for the guy (Woolmer). He has done a lot for world cricket."

But Hussey, who is a key member of Australia's World Cup squad in the Caribbean and captained the side in last month's Chappell-Hadlee series in New Zealand, says security around the Australian team is already excellent and doesn't need to be boosted.

Hussey's comments follow revelations Jamaican police are treating Woolmer's death as "suspicious".

Woolmer was found unconscious in his Jamaican hotel room on Sunday morning and later died in hospital.

Marks were found around Woolmer's throat, fuelling suspicion of foul play.

Rumours have swept the cricket world that the former South African coach was under threat last weekend because of plans to release a book exposing cricket corruption and illegal betting.

"We're very confident we've got excellent security in place. We're very happy with the way everything's been run," Hussey said.

"I don't know too much about it and I know they are doing all the investigations and there are all kinds of words being thrown around.

"But at this stage I'm not wanting to get involved in that sort of stuff.

"All I know is that it is very sad, he was very well-respected around the world for what he's done and as a player as well."

Hussey's Australian team-mate Michael Clarke also said the players had full faith in the current security arrangements, which include a security expert travelling with the squad.

"We can trust Cricket Australia and the ICC to put the security in place for the Australian cricket team," Clarke told AAP.

"It's so sad what has happened and your heart goes out to Bob Woolmer's family.

"But I think we have to continue to trust the security we have around us.

"They have been so good in the past and I'm certain they'll continue to be so.

"So we'll just go about working as hard as we can playing cricket and we'll let the security side continue doing what they're doing."
