As the questions over West Indies captain Chris Gayle's availability for the opening Test of the summer continue to mount, coach David Williams is looking to keep his options open when it comes to selecting the XI that takes on Australia next Thursday at the Gabba.
Gayle returned to Jamaica on the eve of the current tour match against Queensland to be with his sick mother.
The prospect of a replacement player flying out to Brisbane has been floated, but selectors are yet to make a decision.
"We're still hopeful that Chris is going to come back, we're liaising with Chris and hoping that all is going to go well with his mum and he'll be able to return," Williams said.
"We're just playing it one step at a time."
If the visitors take the field next week without Gayle, they will be without their most naturally talented batsman and face a serious selection dilemma as to who opens the batting in his absence.
Openers Adrian Barath (not out 65) and Travis Dowlin (53) both failed in the first innings on Wednesday, but looked a lot more comfortable seeing off the Bulls' youthful pace attack on day three.
However Williams said there were no guarantees.
"It's hard to say."
"We're still trying to formularise our best side and make sure it's well balanced, these are the two openers we have on tour at the moment."
"They look pretty good and we're hoping in the next couple days they will continue to improve and make the selectors' job a tough one."
The other key question is the makeup of the tourists' bowling attack against Australia.
Beanpole spinner Sulieman Benn struggled for consistency against the Bulls, posting the unflattering figures of 1-151 from 34 overs, and Williams would not rule out opting for an all-pace attack.
"We've got to look at the surface and decide on the combinations that we're looking for."
"We'll have a look at the surface before making that assessment."
The pint sized coach was upbeat about his side's prospects for the summer after they moved to 1-133 at stumps and claimed the honours in the final session.
"The players have a fair idea as to where they went wrong and what they need to do."
"It's not about bashing anybody, but we set ourselves high standards and we want to try and maintain them as we go along."
Queensland all-rounder Nathan Reardon celebrated his selection in the ACA All-Star Team for Sunday night's Twenty20 with a maiden first-class century.
The 25-year-old crunched a record seven boundaries in his knock of 147 and was hopeful of reproducing the same magic when he takes on Australia this weekend.
"It's a good opportunity," he said.
"For us young guys who are having our first crack at that sort of level, it means a fair bit to us," Reardon said.
"Hopefully I'll get some runs on the board and put my name in the eyes of the Aussie selectors."
"Hopefully I can get a few in the middle, but I'm not going to put too much pressure on myself."
