WATCH | THIS 102-YEAR-OLD GREAT-GRANNY HAS BECOME THE WORLD'S "OLDEST" SKYDIVER

A 102-year-old great-grandmother is believed to have become the world’s oldest skydiver after plunging 4,300 metres through the South Australian sky.

SA Skydiving has congratulated the great-grandmother on her achievement after she jumped in tandem with an instructor. Centenarian adrenaline junkie Irene O'Shea said she "felt normal" after a 220 kilometre per hour (140 mph) dive that sent her cheeks flapping wildly.

She completed her first skydive to mark her 100th birthday in 2016, but organisers claimed it was Sunday's successful tandem dive at the age of 102 years and 194 days that earned her a place in the history books.

"It was very clear up there, and the weather was good but it was very cold," O'Shea was quoted as saying by the Australian media.

O'Shea's jump was also designed to raise funds for research into motor neurone disease with a gofundme page set up to take donations.
