The 30-year-old helped the Centurions win promotion to Betfred Super League after joining the club midway through 2016 but could not prevent an immediate return to the Kingstone Press Championship last season.
"Warrington's a power club in the Super League and they have a great team for next year," said Brown, who worked under new Warrington head coach Steve Price at Cronulla.
"They had a good base to start with, have recruited strong and with Pricey coming over it's a good opportunity.
"There have been a lot of class players play here, a lot of greats, so it will be very exciting pulling on the jersey and running out at the Halliwell Jones Stadium."
The Australian becomes Warrington's fifth signing for 2018 following the additions of Sitaleki Akauola, Bryson Goodwin, Tyrone Roberts and Ben Murdoch-Masila.
"He's known for finishing tries off and understands the game well," said Price.
"He'll be a great acquisition for the Wolves."
