... brothers claim to have spotted a huge PANTHER on the prowl in rugged bushland

• Men claim 1.5-metre panther was spotted in Victoria's Otway Ranges on Sunday
• Royce and Ben Chaffey spotted numerous animal carcasses throughout the track
• Research indicates that a large cat is reportedly seen in Australia every day 

Twin brothers have claimed they spotted a huge black panther while walking near the Otway Ranges in southern Victoria on Sunday morning.  

Royce and Ben Chaffey, 43, said they also saw a large number of carcasses of various animals throughout the area, which is well known for large cat sightings.

'It was not mistaken for something else, it was a large predator cat,' Royce Chaffey told the Geelong Advertiser.

The twins said the panther was around 1.5 metres in length and jet black in colour.

They claimed to have spotted it as they were standing in the middle of a walking track and tried to capture it on film.
