Esposito joined the Knights in July of this year and caught the eye with a series of impressive performances in the Championship.
The 24-year-old arrived on these shores having started his career in Australia's prestigious Queensland Cup, the competition below the NRL, where he played for the Souths Logan Magpies.
Dario, who becomes the 24th member of head coach Glenn Morrison's new-look squad and the 13th new signing, hails from Wellington in New Zealand but qualifies to play for Italy through his paternal grandfather.
He made a try-scoring debut for the Azzuri in a recent clash with Russia and has high hopes of making the squad for next year's World Cup.
But for now, Esposito says he can't wait to pull on the famous Red, Amber and Black of Dewsbury.
"I met with Glenn a while back and really liked what he had to say in terms of the structure he wants to bring to the club, and I felt it would suit me well," said Esposito.
"I’ve found the Championship to be a fairly physical competition with some strong squads throughout, and I think in 2013 it will be even stronger thanks to the Super League relationships. I hope I can bring some experience to the team. At 24, I'm in the middle of the squad in terms of age and I also hope that my time in the Queensland Cup will help me add some extra value. I can play up front and on the edge and believe that I will offer Glenn a little versatility in that respect."
Rams boss Morrison, meanwhile, says he is confident that his latest recruit will make a big impression at the Tetley's Stadium.
"Dario came to the UK last year and has backed himself to make the Super League," said Morrison. "He played for York in 2012 but knocked back their offer of a new contract because he wanted to play for Dewsbury. He is a skilful front or back rower with plenty of pace and a big enough engine to play plenty of minutes. He's a player who is very committed, and prepared to work hard to achieve his goals."
Meet Dario and the rest of the Rams squad at the Season Countdown evening on November 14.
