Two ACT water police officers launched a jetski rescue mission to save an exhausted kangaroo in the centre of Canberra.

Yet the startled eastern grey proved unwilling when the officers tried to haul it back on to the shore of Lake Burley Griffin.

After its initial rescue, it leapt straight past the police back into the water.

Although kangaroos are known swimmers, witnesses said the female roo had been stranded in a part of the lake where the shores are lined with concrete walls.

A passer-by, Dean Isreb, filmed the rescue attempt, which took place next to the city's parliamentary precinct.

"They went back and got him a second time from the water and some council workers hog-tied him and carried him to their truck," Mr Isreb said.

"But before they got there he shook loose [again] and bounced away toward the High Court … crafty little bugger."

'This happens often'

Kangaroos are capable swimmers, and use rivers, lakes and even the sea to cool down or to escape predators, such as wild dogs.

However, they can become trapped and rangers are often called to rescue them in urban areas.

The president of rescue organisation ACT Wildlife, Marg Peachey, said these events are not unusual.

"Quite often there's a roo in the lake, and it's likely they've gone for a swim or are just moving from point A to point B," she said.

"But if there are people around or they can't get out, they'll need help."

Ms Peachey said concerned onlookers should call a ranger and leave the area so as not to panic a stranded animal.

"The best thing is for people not to stick around, because that's stopping it from being able to get out," she said.
