Portugal’s Correio da Manhã newspaper reported that the couple had died on the Praia dos Pescadores (Fishermen’s Beach) near Ericeira, a picturesque seaside resort on the country’s west coast.
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 taking a selfie on a wall above the beach when they fell.
“Everything seems to indicate that the fall happened when they were probably trying to take a selfie,” he said.
“Since we found a mobile phone on the wall, everything suggests the victims might have been taking a selfie, when they allowed the phone to fall, leaned over to grab it and fell,” he was quoted as saying.
The report did not name the couple but said the woman was 30 and the man 40, although other reports gave slightly different ages. They fell above more than 30 metres, the newspaper reported, adding that a beach cleaner had found the bodies early on Tuesday morning.
The Department of Foreign Affairs and Trade told AAP it was providing consular assistance to “the family of an Australian who died in Portugal”.
It was unclear which of the pair is an Australian citizen.
“The department has been in contact with the British Foreign and Commonwealth Office regarding the other person who died in the incident,” DFAT said in a statement on Wednesday.
