Australian farmers are puzzling over a seal's curious inland expedition far from its watery home as rescuers work to save the marine mammal, local media reported recently.

A dairy farmer in the country's southeastern Victoria state said she first spotted the seal galumphing past bemused cows on August 18.

"We went in the tractor down to the paddock and first thought it was a pig. When it got up and started moving, we saw it was definitely not a pig, it was a seal," Karli McGee told Australia's national broadcaster ABC.

The seal is thought to have traveled about 30 kilometers from its coastal habitat before surfacing on a property in Simpson - about two and a half hours from the city of Melbourne.

"All the locals are in shock. A lot of [the seals] know where we live. We are not near the beach, so it is a bit of a surprise," McGee told ABC.

She said she had contacted authorities and had been told the Melbourne Zoo would assess the animal's health and carry out its rescue.

It was unclear how the seal traveled so far inland, with McGee saying that it may have navigated local rivers before coming ashore in search of food.
