The Oreos are doing the skydive for Telethon Adventures to raise money for childhood cancer by doing arduous and sometimes dangerous adventures.
As well as skydiving, some of the participants climb mountains and walk the Great Wall of China.
Mr Oreo had a few people close to him who had cancer, which is one of the reasons why the family are taking part.

READ NOWThe other reason why the Oreos are taking part is simply that they love adventuring.
Mr Oreo said he was looking forward to jumping out of a plane and leading the dive.
“It has always been in my nature and I am always out and about,” he said.
“We have done adventures for five years now.
“We were the leaders of a dive last year and we are looking forward to doing it again.”
The Oreos will jump out of a plane with 30 sky-divers over Busselton.
The plane will go up to 14,000 feet and fly two kilometres out over the ocean.
The Oreos plan to hover over the Busselton jetty during their dive before landing on the beach.
As well as the dive, the Oreos will also be raising money with raffles down in Busselton.
“It’s good that it is local in WA and reasonably affordable,” Mr Oreo said.
The Oreos currently have five places left.
