Channel Nine's news director Darren Wick confirmed the Triple J newsreader will replace Entertainment veteran Richard Wilkins, who will continue to report on Today Extra.
"I’m really thrilled to be joining the team and so excited to be working alongside Richard Wilkins," Brooke said in a statement.
"He’s such a legend in the business."
Earlier this week, it was announced both Peter Stefanovic and Karl Stefanovic would be stepping down from their roles at Nine.
On Thursday, the TODAY show's Richard Wilkins gave an emotional tribute to his colleague.
“Karl Stefanovic has been a co-host of this great show for 14 years and I’ve had the honour and pleasure, and pressure, sometimes of working alongside him almost every day over that time, and I can tell you from the heart that there is nobody who has worked harder for this show than Karl,” Wilkins said.
