Promising youngster Lachlan Jackson has left Brisbane Roar for the Newcastle Jets.
The 20-year-old made his debut for the Roar last season, making three appearances in total.
New coach Scott Miller said he is excited to have the centre-back at the club.
"In Lachlan we see a player with substantial potential and someone who ought to benefit from being in a full-time environment, learning from experienced professionals in his position, particularly Nigel Boogaard and Daniel Mullen," Miller said.
"He's exceptionally driven and demonstrates sound tactical awareness and composure in possession, which are desirable traits for our club and team.
"While Lachlan starts with us on a one-season contract, we view him as a player who can develop into a regular A-League starter with the club in the coming years."
