The 26-year-old was originally contracted until the end of 2015 but his consistency through this season has earned the Raymond Terrace Roosters junior a 12-month extension.
Browne made his NRL debut in Round 5 of season 2010 against the Warriors and has since gone on to make 35 appearances in the blue and white.
After making 17 of those appearances this year, Browne has grown considerably during his time at Belmore.
“I’m really happy that I’ve been able to extend my stay here at Belmore,” Browne said. “I’ve really enjoyed the last couple of seasons here and to be able to stay is a great feeling.
“I had some tough years with injury but the last couple have been great and I hope I can continue to play consistently under the guidance of Des.”
