NSW premier Gladys Berejiklian has again implored the federal government to keep states better informed of their vaccine rollout plans.
Phase 1a of the nation-wide vaccination program began last week, with healthcare and border workers the first to be jabbed.
But Ms Berejiklian told reporters state leaders are still unsure of how and when the general population will get access to a vaccine.
"I've made no secret of the fact... that we would appreciate as much information in a timely way, but we also appreciate that's not always possible," she said on Sunday.
"Our NSW health officials were able to turn around the Pfizer vaccine supply we've got very quickly - within days - because we've been planning for it."
Of key concern is information about the supply NSW will receive, and at what time, she said.
"I'm not going to hide the fact that our information is key for the states to be able to do our work as best we can."
"The more notice we have the better."
Her comments come as NSW notched up a 42nd day without a single case of the coronavirus transmitted locally.
