They don't make changes because they haven't needed to. Last series I think it was, they went with the classic team of guys who've always done the job in the past, they lost game 1, looking pretty tired after NSW's forward pack ran over them & what do you know, they made instant changes to get some younger, fresher forwards in the side. If Queensland lose badly in the first game, there'll be great temptation to bring in some young blood, though I still think Ponga would be a 50/50. You never know though, Queensland might still just whoop our asses 3-0 & won't need any changes.
