Zaza Bedford is from Munda, Western Province and New Zealand and is part of the Dive Munda scuba diving centre.
The 19-year-old qualified through Scuba Schools International and can work worldwide as an instructor.
Operations manager of Dive Munda Belinda Botha said she had been grooming Ms Bedford as an instructor for the last 18 months.
"Zaza came to me, 18 years old, just fresh out of school and never dived before," said Ms Botha.
"It was first of all getting her comfortable in the water and luckily it was her passion as well," she said.
