St George Illawarra have won through to the National Rugby League grand final after coming from behind to beat Wests Tigers 13-12.
Jamie Soward slotted a field goal at Sydney's Olympic Stadium to seal the win and put the Dragons through to a decider against the Sydney Roosters next weekend.
The minor premiers were behind 12-6 at half time but employed their characteristic grind to haul themselves over the line and reach a first decider since 1999.
With the scores locked at 12-12 from the 50th minute, Soward clinically slotted over from 33 metres out in the 74th to end the Tigers' first finals campaign since a premiership victory in 2005.
The Dragons made the second-last week in both 2005 and 2006 and exited in straight sets last year despite winning the minor premiership in their first season under six-time title-winning coach Wayne Bennett.
The Dragons, as pre-merger St George, last met the Roosters in a grand final in 1975 while they haven't won a competition since 1979, losing five grand finals as both entities after that success.
