Philippines authorities reveal details about accused Bondi Beach gunmen's month-long stay in Davao City, pushing back against terrorism training claims.

Australia's Prime Minister Anthony Albanese said that the terror attack on Jewish people at Bondi Beach was "motivated by ISIS ideology."

Sajid and Naveed Akram stayed for a month in a £11-a-night hotel in Davao, one of the largest cities in the Philippines on an island hotbed of Islamic extremism

MANILA, Dec 17 (Reuters) - There is no evidence indicating that the two suspects involved in the Bondi Beach attack received any form of military training while in the Philippines, the Philippines' National Security Adviser said on Wednesday.

Alleged terrorists Naveed and Sajid Akram spent almost a month holed up in a small hotel room in a city in the southern Philippines in the lead-up to the attack, local staff have said.

Investigators are probing a trip the father and son alleged to have carried out the attack took to the Philippines. The Sydney Opera House was lit up with a menorah overnight in a message of support and solidarity to the Australian Jewish community.

The attack was Australia's worst mass shooting in nearly 30 years, and is being investigated as an act of terrorism targeting the Jewish community.

The death toll of the horrific Bondi terror attack has risen to at least 16 people, including a 10-year-old schoolgirl, with fears the number of victims will continue to grow. Sky News Australia has rolling coverage of the tragedy.
