The Queensland Rugby League is likely to oppose extra time for this year's State of Origin series at a meeting in Brisbane on Thursday, plunging it into a boardroom battle with its NSW counterpart.

The QRL - and Queensland coach Wayne Bennett - have publicly rallied against extra time, but pressure is mounting on the Maroons to endorse it following the National Rugby League's decision to adopt it for premiership matches.

QRL managing director Ross Livermore admitted as much on Wednesday and said the Origin series and extra time would be high on the agenda tomorrow.

"We haven't had a meeting since it was adopted by the NRL for the local competition," Livermore said.

"Our view has been well documented in the past. Whether it changes because the NRL has decided to do it for their competition (we'll see).

"You try to be consistent because the players that play in that competition (the NRL) are going to play in Origin. But the Origin is a little different."

If the QRL rejects extra time, it will almost certainly be at loggerheads with the NSW Rugby League at next month's Australian Rugby League meeting.

The NSWRL is almost certain to endorse extra time for this year's Origin series at its board meeting next week.

A final decision will be made at the next ARL board meeting on March 4, with NSW having the numbers to push it through if the two leagues are stalemated.

"I think we have to go with it...just for consistency, that's my personal viewpoint," NSWRL general manager Chris Turner said.
