A NSW man was working in his shed outside his home when he heard a strange noise outside.
The man told The Sydney Morning Herald that he opened the door of his shed and spotted a gigantic lizard scooting across his yard and out of sight.
The man told the Sydney Herald he lived in the area for 18 years, and he had never seen anything like it.
He continued puttering around in his shed when he heard a distinct banging noise on the side of his house.
When he went to investigate, he spotted the same monster chilling on his wall. The banging noise was the monster lizard’s tail hitting against the drain pipe.
The man snapped a picture of the thing and posted it on Facebook, where it went viral.
According to the Sydney Herald, the lizard is a Lace monitor, also known as a Lace goannas. It can grow up to 7 feet and weigh up to 45 pounds. This particular specimen is 5 feet long.
