Sporting nothing more than a body suit and a snorkel, the 29-year-old heads down to the sea bed.
In the clip, you see a small gap in the rocks, which she fearlessly explores.
She peaks inside it and holds her breath for what feels like forever as she progresses through.
Then she finally emerges and floats back up for air.
