Emergency services were called to Darling Downs Zoo in Pilton, south of Toowoomba, on Sunday morning after the woman was attacked in an enclosure by one of the big cats.
The zoo said the woman, who emergency services said was in her 50s, was watching other keepers in the area home to its carnivores when she was attacked.

The zoo did not say which animal attacked her but it is home to lions, cheetahs and a tiger, according to its website.
Investigators were seen paying close attention to a lion enclosure where the woman is believed to have lost her left arm.
It called her a "member of the family" but didn't say she worked there.
"This is something that she has done many, many times over the past 20 years," the zoo said on Facebook.
"She is well versed in safety protocols around potentially dangerous animals.
"Inexplicably, at this stage, one animal grabbed her by one arm and caused severe damage to it."
9News understands she was saved by the quick actions of an employee who used a belt to tie a tourniquet.

It also said the animal had not recently had cubs.
Queensland Ambulance confirmed the woman had suffered a "significant arm injury" following an animal bite.
The zoo said it would wait to interview the victim to assess exactly how the attack happened.
