"Thank you for your patience and understanding as we work through a very difficult process."
No date has been set for funeral ceremonies, but Mr Willie said the families would lay the victims to rest in Cairns early in the New Year.
He said those affected by the tragedy had been offered tremendous support from community leaders and organisations, individuals, agencies, and the private and corporate sectors.
"Our priority focus to date has been very much towards supporting our traumatised family members, to meet our cultural protocols and to begin to consider extraordinary funeral arrangements," he said.
Mr Willie urged the wider public to band together during the Christmas period and "hold dear such occasions with family and friends".
Families needed to regularly offer and seek loving support from one another, he said.
"Children are the most vulnerable of our society whose innocent lives deserve the greatest of love and care," he said.
"Cherish them."
