The text of tribute messages has been projected onto buildings in Sydney, to mark the first anniversary of the Lindt cafe siege.
It is a year since a fatal hostage situation at the cafe in the Australian city left several dead and wounded.
18 people were taken hostage at the Lindt cafe by an armed man brandishing an ISIL flag.

The cafe manager died, along with a customer. The gunman was also killed.
A court hearing is underway to determine whether the act was directly linked to ISIL or whether the gunman held a personal grievance.
Dignitaries visited the site and were shown a model of a permanent memorial planned for the site.
Clear cubes containing flowers will be set into the granite paving in Martin Place.
