Watson completed light running drills before another lengthy batting nets session on Saturday as he recovers from a hamstring injury ahead of the first Gabba Test starting on Thursday.
The all-rounder said he held out hope that he could bowl in Brisbane but would await the opinion of team doctor and former Liverpool FC physiotherapist Peter Brukner, who arrived on Saturday.
"He has certainly given me great advice over the last six months especially with my body," the injury-plagued Watson told reporters.
"I am confident I will be there as a batsman. To play as a bowler would be an ideal scenario.

"From previous experiences I will err on the side of caution.
"But if my body is right to go that's what I will be doing (bowling)."
But team bowling coach Craig McDermott was not too sure about Watson's chances of bowling if he played in the Gabba Test.
"We will wait until the day before the game to see where he is with his bowling," he said.
Hamstring injuries have been common for the former vice-captain -- he missed the 2006-07 Ashes campaign with one -- and there has always been a question over how to balance his workload as an all-rounder.
