Police numbers have been increased across Sydney in response to yesterday's cafe siege which left two people dead, senior New South Wales officers have said.
There will be an increased police presence in public places, transport hubs and iconic locations such as the city's harbour.
Mick Fuller, the force's assistant commissioner, said the aim was to ensure all residents felt safe "during these testing times".
“We want the community of Sydney and for that matter NSW, to go about their day to day business with confidence and comfort in the knowledge they are safe,” assistant commissioner Mick Fuller said.
The New South Wales Police commissioner said he "couldn't be sadder" following the deaths of two hostages in the Sydney cafe siege.
Andrew Scipione told reporters: "It's incredibly sad - I don't think I could be sadder."
A Sydney DJ who spoke to one of the hostages trapped in the Lindt Chocolate Cafe has recalled the demands made by the lone gunman.
Ray Hadley told Good Morning Britain one of the hostages called 2GB radio station where Mr Hadley works, and relayed demands made by Man Haron Monis.
"He wanted an ISIL flag - pretty simple requests - he wanted to speak to the Prime Minister for five minutes. And he wanted the government...to say it was an ISIL terrorist plot and he wanted that broadcast on the radio."
The gunman nehind the Sydney café siege, Man Horan Monis, was not on a terrorism watchlist, Australian prime minister Tony Abbot has revealed.
He was, however, "well known" to police, Mr Abbott added.
Australian Prime Minister Tony Abbott has warned that people face a "very real threat" from extremists.
In a press conference after the 16-hour siege at a café in Sydney, Mr Abbot said there were people with the "will and capability" to carry out terrorist attacks in the country.
He said he shares people's "outrage" that gunman Man Horan Monis was allowed out on bail despite being implicated in a string of serious offences, and vowed that an investigation would be launched.
But he told reporters that he believed even if Monis had been under 24-hour surveillance, the seige may still have happened.
