Sea turtle washes up in Victoria

An exhausted green sea turtle has been found on a Victorian beach, thousands of kilometres from its tropical home.

The 10-year-old, 7kg green sea turtle was found severely dehydrated, weak and bruised, in a rockpool off Mt Martha beach on the Mornington Peninsula last week.

Steve Le Nepveu, a vet with the Mt Martha Veterinary Clinic, didn't expect to see a sea turtle this far south.

"It's probably got itself lost and couldn't fight against the currents and (it's) been dragged down the country," Dr Le Nepveu told AAP on Friday.

"When a member of the public called to say they found a turtle, we were expecting something considerably smaller, certainly not a green sea turtle. It was a first for me."

The turtle was transferred to a Frankston clinic with a reptile specialist, who put it on a drip and began treatment for "cold shock", before transferring it to Melbourne Aquarium for rehabilitation.

The turtle is reportedly doing well and is expected to survive the ordeal.
