The thousands of flowers that Australians offered for the two victims of the Sydney Siege weren't thrown into a regular landfill when New South Wales cleared the temporary memorial set up in Martin Place.

The sea of colourful bouquets, estimated to reach 100,000, would be turned into compost and be part of a garden that comprise a forthcoming permanent memorial the Australian state would build still at Martin Place.

NSW Premier Mike Baird said the permanent memorial would be for the victims, hostages, cops and emergency service workers. To make that possible, he created a Martin Place Siege Memorial Committee to be chaired by the Department of Premier and Cabinet.

The committee is tasked to come up with designs, after consultations with the Sydney City Council, hostages who survived and the families of Tori Johnson and Katrina Dawson who sacrificed their lives so fellow hostages inside the Lindt Café would live.

Baird said the permanent memorial would be ready by the first anniversary of the siege.

He said that Sydney is continuing the healing process started with the sea of flowers brought at Martin Place with the unveiling of the permanent memorial which would also "guarantee that the memory of Tori and Katrina lives forever in the heart of Sydney."

The investigation is still ongoing to determine how the two died at the end of the 16-hour hostage crisis stated on Dec 15 by migrant gunman Man Haron Monis.

Tori's family said they agree with the idea of a permanent memorial and are eager to assist in its planning. Katrina's family set up a foundation that would focus on women's education.

Martin Place has become the hot spot where to remember victims of global violence such as the Paris Massacre as Sydney residents again gathered in the area on Sunday afternoon to remember the slain Charlie Hebdo workers.
