First day on job for new NSW top cop

NSW police commissioner Mick Fuller says he'll focus on tracking down extremists committed to lone wolf attacks as he takes on the role of the state's top cop.

The former assistant commissioner will officially take over from Andrew Scipione on Monday.

Mr Fuller, who started out as a junior officer in 1987, brings 16 years' operational policing experience to the role and has proposed an extensive reform agenda.

He's pledged to establish a team to work with other government agencies, in an effort to target extremists and prevent terrorist attacks.

One of Mr Fuller's first challenges will be responding to the findings of the Lindt Cafe inquest, expected within weeks, and he promised not to "drag the chain" on suggested changes.

"We will face the good and bad in that," he said.
