Kate CJ Murphy, president of Townsville Bat Rescue Australia, posted a video to the organization's Facebook page showing the black flying fox swimming in the pool, unable to get out.

"She was about two months old and probably just testing her wings, trying to fly for the first time away from mum," Kate told news.com.au.

"We get a few two to three-month-olds flying for the first time, and they get themselves in odd positions."

"Bats fly down to rivers to skim the water to drink, they don't hang still and drink -- they skim down as they're flying. [And] the lap pool looks like a river to a bat who is learning about life," Murphy said.

"Before we had all this rain in Townsville we had extreme heat and she possibly thought it was a good place to have a drink."

The small bat can be seen gliding through the water in the pool appearing to do breaststroke as she moves quickly for the side to get to safety.

Murphy explained that the hotel is located near mangroves that are home to a large number of bats.

Following the rescue, Murphy, one of five volunteers at the not-for-profit group, kept the bat in her care for 24 hours, where it was monitored for symptoms of pneumonia.

As the bat is so young, Murphy has explained that it'll likely get lost if released where she came from.

Instead, Murphy has put her with a release colony that she's "already got [so] she will be released with about 30 other friends because they're mob animals."
