The suspect in last week at a hotel in a popular resort city south of the Philippine capital has surrendered, officials say.
Police said the man was a former hotel pool cleaner who wanted revenge for his dismissal.
The bodies of the victims, whose hands and feet were tied, were found sprawled on the floor in a room at the Lake Hotel in Tagaytay City a week ago.
The victims were identified as David James Fisk, 57, and his wife Lucita Barquin Cortez, 55, a Philippine-born Australian citizen.

The identification of the suspect eventually led to his home province of Batangas near Tagaytay where he decided to surrender, Capagcuan said.
Tagaytay mayor Abraham Tolentino and Capagcuan presented the handcuffed suspect, wearing a hoodie, dark eyeglasses and a face mask, at a news conference. The man's name was not announced.
Officials planned to file criminal complaints of robbery in addition to the killings against the suspect, who allegedly acknowledged he took the watch and shoes of the Australian man after attacking him with a knife and suffocating his partner, and her Filipina daughter-in-law, Capagcuan said.
