He took the photograph of the UFO at 4.25pm on Wednesday, December 5 in perfectly clear conditions.
Mr Isaacson now wants to know if anyone else saw anything else unexplained flying around the Dudley Peninsula or Kangaroo Island in the past few weeks.
“Just when I stopped taking photos and moved the camera down, I saw something out of the corner of my eye,” he said. “Whatever it was moved silently and exceptionally quickly.”
He didn’t realise he had captured the object on his camera until he got back to his accommodation and started downloading and going through his photos from the day.
His only thought was that it could have been some kind of unmanned drone, as it did not move like a plane or helicopter.
He said it appeared to be about a “football field” distance off the shoreline below the lighthouse.
“I’d be interested to know if anyone else reported a sighting that day,” he said.
Mr Isaacson was originally from Sydney but now lives and works as an interior designer in Berlin, Germany.
He was on Kangaroo Island with his mother who was celebrating her 90th birthday and were staying with friends at the Seaview Lodge in Penneshaw.

The Islander last reported on KI UFO after National Geographic published an article about an explained sighting over Kangaroo Island in 1969.
There have been numerous other UFO reports over the years reported in this newspaper.
Have you ever seen any usual activity in the skies above Kangaroo Island?
