Yesterday, Peter Trembath, the vessel's operator, said Ms Hawkes' injuries were not serious and only required cleaning and stitches.
"We're pleased she's been discharged and we're expecting her to make a speedy recovery.
"She loves her job and loves what she does, and I expect she'll be back at work as soon as she can."
Mr Trembath said crew members had checked the crystal-clear pool and seen no crocs, but obviously one was there.
"As Tara was getting out of the water it latched on to her leg, but fortunately it wasn't a very big animal."
Mr Trembath said the animal might have been a big freshwater croc or a small saltwater one.
"Freshies don't normally bite unless you step on them or if you corner them, which could have happened as she stepped out of the water."
In a separate incident, a 2m crocodile was reported to have attacked a car north of Mackay in Queensland.
Environment department officials said the reptile's lunge at the vehicle was likely a "defensive action".
He said authorities did respond to the report, but police had advised that the croc returned to a creek of its own accord. Authorities said they did not believe the reptile posed an ongoing threat.
The driver of the car was not injured.
