A young Irish tourist was nearly three months into her dream Australian working holiday when she was found unconscious on the ocean floor off the north Queensland coast two days ago.
Elaine Morrow, 23, had described her Queensland adventure as "glorious" just days before she drowned at the popular tourist destination.
The recent university graduate left her job in medical diagnostics and travelled from her Northern Ireland home town of Ballintra to Sydney in January.
She dreamed of spending a year in the surf, sand and sun and would have been in Australia for three months today.
In messages to friends on social networking site Facebook last month Ms Morrow said she was relishing her time Down Under.
"Sitting in the sun with no worries," she wrote. "Drinks on Bondi tonight and may be head out to the island tomorrow! It's a tough life."
The National University of Ireland graduate had worked at Cafe Bondi for several weeks before leaving for a short holiday in Queensland.
Cafe manager Kerry Gu said Ms Morrow was a "happy, very nice and quite chatty" woman.
"It's just so sad. It's hard to believe," she said.
"She had only worked a couple of shifts with us. She was lovely and easy going. I believe she wanted to stay here for a year."
Fellow waiter Gus Lambert said he too remembered Ms Morrow as a "bubbly person".
"She was always in a good mood," he said.
Ms Morrow was on a roadtrip with friends and had travelled from Sydney to Byron Bay before moving on to Fraser Island and the Whitsundays.
In her final Facebook message last Friday Ms Morrow wrote, "Now its time for the Whitsundays ... three glorious days on a lovely boat!"
Her holiday was tragically cut short on the second day of the three-day charter with friends on the boat Summertime, when she failed to resurface during the introductory "resort" scuba dive.
Frantic fellow divers tried in vain to resuscitate the young tourist after pulling her body from the water.
She was then taken to Hayman Island Medical Centre where a nurse tried to resuscitate her, but Ms Morrow could not be revived.
It's not yet known why the 23-year-old suddenly drowned, although a post mortem examination is underway today.
Sergeant Graeme Pettigrew of Whitsundays Water Police said initial investigations suggested Ms Morrow had become separated from the group while diving and failed to resurface with the other divers.
"The person involved was on a resort introductory dive. She was not an experienced diver," he said.
"She became lost from the group."
The charter boat docked yesterday at the Abel Point Marina, Airlie Beach, where crime investigators examined the vessel.
The boat's operator Whitsundays Sailing Adventures said its practices were to the highest safety standards.
“All of our tours are operated to the highest safety standards. The operator involved carried out all emergency procedures including CPR, but unfortunately the young lady could not be revived,” the company said in a statement.
“Whitsundays Sailing Adventures and the vessel operator are currently working with the appropriate authorities in regards to this incident.
“Our condolences go out to the family and friends, and counselling support is being given to the other guests and crew of the vessel.”
Ms Morrow's parents Margaret and James and her two sisters are understood to be receiving consular assistance.
