Gerard Sutton and Ashley Klein have been appointed the on-field referees for the opening match of the 2019 Holden State of Origin series at Suncorp Stadium.

Sutton will be the lead referee with Klein taking assistant referee duties, while Chris Butler and Nick Beashel will be the touch judges for the game and Jared Maxwell and Ben Galea will operate the NRL Bunker.

It'll be Sutton's 14th straight State of Origin match while Klein will officiate his sixth game on the Origin stage.

"All of our officials, but particularly the two referees, are experienced in big games," referees boss Bernard Sutton said.

"The two referees officiated in the three Origins last year, as well as the grand final.

"It's clear they have the experience required to officiate on the biggest stage, and they have refereed well as a partnership."
