While investigations continue, Corfina Media reported police have ruled out murder as a possible cause of death.
Michael Kearns, 33, was holidaying with his partner Louise Benson, 37, before the pair were found dead on a popular surfing beach in Portugal.
Reports said two Australians may have been taking selfies when they fell about 30 metres in the town of Ericeira.
A couple said to be from Australia and the United Kingdom were presumably taking a picture on a 30-meter-high wall overlooking a picturesque beach when they allegedly lost their balance and fell off a cliff in Portugal.More news: Singer, 13, earns Howie Mandel's golden buzzer on America's Got Talent
It was not the first time that tourists had fallen off the wall.
Rui Pereira da Terra, the head of the rescue service in Cascais port near Lisbon, told the news agency Lusa that officials suspected the man and woman had been posing on a wall above the beach when they fell.
The beach at Pescadores is surrounded by cliffs and a 30-metre high wall covered in shrubs.
"It seems that (the victims) might be getting a "selfie", when they let the phone fall, leaned over to grab it and fell", he was quoted as saying.More news: Driver Power Rankings after 2018 FireKeepers Casino 400 — NASCAR Cup Series
The spokesperson did not confirm the nature of the incident or say how the woman died.
Local media reported the pair were both Australian, however, the Department of Foreign Affairs and Trade said one Australian had died, and the department had been in contact with its British counterpart over the second death. "Owing to our privacy obligations we will not provide further comment", a DFAT spokesperson said.
It is a popular hotpot, with countless tourists uploading their pictures of the enormous wall on Instagram.
