St George Illawarra fullback Matt Dufty has re-signed with the Dragons for a further two seasons.

Dufty – who was already under contract for 2019 – will now remain at the Dragons until at least the end of the 2021 NRL Telstra Premiership season.

The Penshurst RSL junior's remains excited by the upcoming season, as competition for positions heats up leading into the pre-season trials following Corey Norman's arrival to the Red V.

"I'm very happy about re-signing for another two years. It wasn't a difficult decision. The Dragons is somewhere where I think I could play my best footy and where I wanted to stay," Dufty said.

"I feel like a weight has been lifted. I've had it over my head for a while now and I'm glad the positive discussions I've had with the club has ended this way.

"I'm really excited for this year to come. I'm not sure where I'll play but it's a good headache for Mary (coach Paul McGregor) to have.

"We have all been playing different positions, trying to get our different combinations sorted and with the strike force we have, it's exciting to see how we all play."

Dragons Director of Rugby League Pathways and List Management Ian Millward was pleased the 23-year-old Dufty decided on recommitting to the club.

"He's a local junior who has gone through our pathway system, and we know he's a person we want here long-term at this club. He's a passionate Dragons player who brings a real skill set to the team," Millward said.

"We have been in deep discussions and negotiating with Matt and his agent since last year. He was aware of our discussions with Corey Norman at all times and he knew where his future lied at our club at all times.

"As for this year, we're really excited by 2019 with the depth and quality of our roster. In regards to what positions everyone plays, that's up to the coach. [The coach] is excited by not only the spine he has in 2019, but also 2020 and 2021."

Dufty's re-signing follows the recent key reacquisition of Tariq Sims until the end of the 2022 season.
