Republican campaigners say the Harry and Meghan interview shows the royal family is dysfunctional and has bolstered their cause, but Daily Telegraph readers disagree.
Australian Republican Movement chair Peter FitzSimons welcomed the NSW minister's support following the Sussexes' bombshell interview.
"Minister Kean is one of our biggest supporters … it's wonderful to see parliamentarians of all persuasions pushing for this truly Australian cause," Mr Fitzsimons said.
"It reflects the growing support for a republic in the community and the view of many that it's time."
Mr Fitzsimons said the interview "played" in pro-republicans' favour, with Meghan and Harry's claims proving Britain's monarchy was no longer fit to oversee Australia.
