A win on Sunday would secure New South Wales a rare State of Origin series win in front of their home fans.
The last time they won the series was in 2014, when a late Trent Hodkinson try sealed a famous victory.
But heading into Game Two of the series with a lead is nothing new for 'The Cockroaches' - quite often they have snatched defeat from the jaws of victory.
Newshub takes a stroll down memory lane on the last FIVE times New South Wales held the lead and blew it.
2017
Only last year, New South Wales started the series with a bang, as James Tedesco, and Andrew Fifita starred for the Blues in a 28-4 win at Suncorp Stadium.
The encounter is remembered for its frantic play with very few stoppages.
The Blues continued their form from the first game in front of their home fans and took a 16-6 lead at the break. Just as NSW fans started to believe they would reclaim the shield,
But Queensland found their vintage form and kept Laurie Daley's side scoreless in the second half to win 18-16.
In Game Three, a hat-trick to Valentine Holmes was enough for Queensland to claim a 22-6 win that kept the shield in the north for the third straight year.
2013
James Maloney made his Origin debut in Game One and anchored the Blues attack to a 14-6 win.
The game held controversy, after Paul Gallen punched Nate Myles and wasn't sent off. That led to the NRL introducing an automatic sin bin for anyone throwing a punch.
After losing the opener, Queensland made several changes, while the Blues had three players stood down for separate incidents.
A brawl broke out in the second half, when Queensland led14-0 and that saw two players from each state sent to the bin. But that didn't matter, as the Maroons won comfortably 26-6 in Brisbane.
In Game Three, the Blues came so close to ending the streak, but again fell agonisingly short, as they fell 12-10. A 13th-minute Thurston penalty goal ultimately proved the difference between the two teams in another thrilling series, as Queensland won the shield for the eighth straight season.
2008
Queensland came out swinging to start the series, but the Craig Bellamy-coached Blues were well prepared and spent large portions of the encounter successfully defending their line.
Eventually, the Maroons ran out of gas and the home side prevailed 18-10.
In Brisbane, Game Two was the complete opposite, as Darius Boy touched down twice on debut in a 30-0 romp over the Blues, who couldn’t catch a break in this encounter.
NSW were confident heading into Game Three, due to Queensland's poor record in deciders at Sydney. It was a titanic tussle early on, as punches were exchanged in the contest.
Both teams headed to the sheds locked at 10-10 and the scores hadn't changed heading into the final quarter, as both sides began to think the next team to score might win.
The deadlock was broke in the 67th minute, when Jonathan Thurston made a break from his half and sliced through the defensive line, before passing to Billy Slater, who scored the match-winning try under the posts.
2006
The Blues were hunting for their fourth straight series win, and things got off to a great start, when late call-up Brent Finch kicked the match-winning field goal from 35m out to seal a 17-16 victory.
Darren Lockyer's commanding man-of-the-match performance propelled the Maroons to a 30-6 win in Game Two at a man of the match performance in Brisbane.
That set up a deciding encounter in Melbourne. After 73 minutes, it appeared the trophy would remain in Blues country, as they held a 14-10 lead.
But a wayward pass from fullback Brett Hodgson was scooped up by Lockyer, who scored to give the Maroons a late and dramatic 16-14 win.
Blues coach Graham Murray describes it as "That Pass" that ultimately changed the State of Origin, as the series win was the beginning of Queensland’s eight-year dominance.
"I was gutted," said Murray. "We led 14-4 with nine minutes remaining.
“Queensland then scored a length- of- the field try to make it 14-10... then there was 'That Pass'.
"It was shattering, because we were close enough to win it.
"Someone at the time said Origin always throws up the unexpected."
2002 (draw)
Queensland headed into the series after winning the previous year and that proved to be crucial to for how the series played out.
The Phil Gould-coached Blues started with a bang, as Andrew Johns led the home side to a 32-4 in Game One.
But in typical Queensland fashion, they bounced back in Brisbane, as Lote Tuiri scored three tries and kicked three conversions in a 26-18 win.
Game Three of the series is well remembered for Gorden Tallis' famous tackle on Hodgson, where he picking him up like a rag-doll to drag him into touch.
Late in the game, the Blues thought they'd won the series, when Jason Moodie scored with three minutes to play for an 18-14 lead.
But Queensland forward Dane Carlaw made a break down the wing to score on full- time, which resulted in the series ending in a draw.
The Maroons held onto the shield, as they were the current holders.
