The Daily Mail reported that she was still alive when rangers arrived about 50 minutes later and she was able to talk to paramedics but not long after she died at the scene.
Ms Woolmer was in Australia on a 12-month working visa when she fell to her death in June last year.
She was on a trip of a lifetime, the Daily Mail reported.
Ms Woolmer's friends and family took to social media to express their sadness after the incident.
Her mother Dawn wrote on Facebook: "It is with a heavy heart that our family and friends report the sad loss of our dear Zoe during her much loved trip to Australia. Words fail us during the difficult time."
Ms Woolmer's friend Connie Patterson wrote on Facebook of her: "I miss you like crazy and cannot ever put into words how much I love you and the great experiences we have shared together!"
A number of photos of guides and walkers posing on the ledge were posted to the company's Facebook page, but were removed following Ms Woolmer's death.
