Relatives of Tori Johnson and Katrina Dawson, the hostages killed in the Lindt cafe siege, have visited a memorial to victims at Martin Place in Sydney.
The families were among thousands of mourners paying their respects on Wednesday.
Tributes continue to flow for Mr Johnson, 34, manager of the Lindt Cafe where gunman Man Haron Monis held the hostages for 16 hours, including Katrina Dawson, 38, who was also killed.
Fifteen other hostages survived the ordeal.
Masses of floral tributes have been left by members of the public in what has become a spontaneous memorial at Martin Place, with condolence books also available for people to sign.
Mr Johnson’s father, Ken Johnson, kissed flowers before throwing them onto the shrine.
“It’s a very moving moment … very moving,” he said.
“Thank you everybody for supporting us.”
Ms Dawson’s brother also visited the memorial with his family.
Prime Minister Tony Abbott visited Martin Place on Tuesday afternoon to pay his respects to the victims.
He said it was one of the most difficult periods in Australia’s history.
“This is an incident which has echoed around the world,” he said.
The Federal and New South Wales governments have ordered an urgent review of the Martin Place siege which will examine a range of issues including why the gunman was granted citizenship in Australia and what information security agencies had about him.
Mr Abbott announced the review on Wednesday afternoon, saying there were questions “begging” to be asked.
