'It's a horrible feeling': Residents stunned by apparent 'suicide pact' on exclusive Gold Coast island

Residents on an exclusive Gold Coast island have told of their shock as police on the Gold Coast investigate three mystery deaths there after an elderly mother and her two adult daughters died in an apparent suicide pact.

The Gold Coast's Ephraim Island boasts a lavish and secure community consisting of multi-million dollar apartments, with plenty of space to park a yacht on pristine blue waterways.

But the isolated community accustomed to comfort and pleasure was shaken Tuesday by the news three of their residents, all from the same family, had taken their own lives.

Margaret Cummins, 78, and her daughters Wynette and Heather, aged in their 50s, are reported to have taken their own lives after they were discovered after 3pm Tuesday.

Heather's husband returned from a trip to the shops to find the three women dead from an apparent suffocation.

"He is pretty shaken. He wasn't aware that this was culminating today," Inspector Jim Plowman told the Courier-Mail.

The detective said there were no suspicious circumstances surrounding the deaths as it was "fairly obvious" how the women died.

The three bodies were found in the luxury apartment on the island.

Detective Senior-Sergeant Mark Procter of the Coomera Crime Investigative Branch said all three women died in a similar way in the same unit and it is believed all had medical issues.

The investigator said the husband was "not surprised that has happened, I think he's surprised it's three of them at once".

Local residents told the Gold Coast Bulletin the mother had been living on the island with her disabled adult daughter for a number of years before Heather and her husband arrived 12 months ago.
