4BC Drive: Queensland is still at odds with the federal government on how to change Australian laws to allow Prince William and his wife Catherine's first child to become the monarch whatever the gender.
Leaders at the Commonwealth Heads of Government Meeting (CHOGM) in Perth last year agreed in principle to change laws relating to Britain's succession.
A monarch's firstborn son becomes heir to the throne under current laws.
Under proposed changes, a firstborn girl would automatically become heir ahead of any younger brothers.
Prime Minister Julia Gillard said the most legally effective way to deal with the change was for the states to pass legislation to allow the commonwealth to make the changes to succession.
"For that to be a legally effective process, all states have to do it. If one state doesn't do it, then it doesn't work," Ms Gillard told reporters in Canberra after the COAG meeting on Friday.
Listen: Gary Hardgrave on the succession legislation.
Queensland Premier Campbell Newman said his state had a different view from the federal government and all the other states.
"Our view is that we will pass legislation in accordance with our position as a separate sovereign state," Mr Newman told reporters in Canberra.
"We're a federation of states. We're going to do it the right way, the proper way and that's our view."
Mr Newman did not disagree with the succession changes.
"It doesn't stymie it. We believe the end objective is achieved by the states passing their own legislation and the commonwealth," he said.
The proposed changes will also remove a bar on succession by a royal who marries a Catholic.
The Duke and Duchess of Cambridge's firstborn will be third in line to the throne behind his or her grandfather, Prince Charles, and father Prince William, bumping Prince Harry to fourth in line.
If there was one thing the leaders at COAG agreed upon, NSW premier said it was that everyone was "very happy" the royal couple were expecting a baby.
