Australia's terror alert level remains unchanged despite warnings of increased "chatter" and the arrests of two young terrorism suspects in Sydney.
Authorities say an attack remains likely but not imminent, with police and Foreign Minister Julie Bishop saying people should carry on with Christmas plans as usual.
The two terror suspects will remain behind bars over the holiday period after they were refused bail at Parramatta Local Court on Wednesday.
The men were arrested on Tuesday following raids on Thursday conducted as part of counter-terror operation Appleby - the same team that undertook sweeping pre-dawn raids in Sydney in September.

One of the men, Sulayman Khalid, 20, of Regent's Park, allegedly had documents naming government targets for potential terrorist attacks.
The documents were found along with a rifle and two shotguns, police allege.
A second man, 21, is accused of breaching a strict control order handed down following the raid by making unauthorised phone calls.
Australian Federal Police Deputy Commissioner Michael Phelan said he was confident that police had disrupted "the activity they were planning".
He declined to go into detail, but said there was no threat of a specific terrorist attack.
Eleven people had been charged under Operation Appleby, which has targeted a nameless group of up to 20 people who sympathise with militant group Islamic State, Mr Phelan said.
He added that Prime Minister Tony Abbott was "absolutely right" to warn the public about heightened terrorist "chatter" in the aftermath of the Lindt Cafe siege tragedy in Sydney.
"We don't know when and how an attack may come, but we do know there are people with the intent and capability to carry out further attacks," Mr Abbott said on Tuesday.
Mr Khalid had a brief brush with fame in 2014 when he stormed off the SBS show Insight while being investigated over the reported cancellation of his passport by security agencies which feared he would head abroad to fight.
The other man, who cannot be named for legal reasons, is only the fourth Australian to be handed a control order - a zero-tolerance restriction of a subject's activities.
Former Guantanamo Bay inmate David Hicks was handed one in 2007.
