Steve Waugh has only five days to tell national selectors whether he wants to continue his Test career in the Caribbean next month.

The selection panel must know by Sunday, with a likely phone hook-up later that night to determine the 15-man squad to confront the West Indies in four Tests.

Waugh's plans aren't known and he again brushed off questions at a press conference on Tuesday ahead of Friday's Pura Cup final between Queensland and Waugh's NSW at the Gabba.

"No comment. I'm here to talk about the NSW game," Waugh told journalists.

Blues coach Steve Rixon wants Waugh to play in the Caribbean after the 37-year-old unleashed three centuries for NSW in the last five weeks.

"He's in sensational form and he would be a blessing to have in any one of those sides over there in the one-day comp right now (World Cup) and, more importantly, any four-day side or any five-day side," Rixon said.

"He's going to continue to do the business ... it's really whether Stephen himself wants to go on and no one really knows that."

National selector Trevor Hohns said he would speak with Waugh in Brisbane later this week, with the captain's future to affect the make-up of the squad.

If Waugh plays on for Australia, the race for a reserve batting spot will become even tighter with rising NSW star Michael Clarke further enhancing his claims.

Clarke and Queensland pair Martin Love and Ashley Noffke can boost their claims during the Pura Cup final, although Hohns expected most of the selection issues were already settled.
