Aaron Mooy has joined fellow Socceroo Mat Ryan at Brighton and Hove Albion on a one-year loan deal after signing a new contract with Huddersfield Town until 2022.
The midfielder emerged as a target for the Seagulls this week and will make the temporary switch to Brighton for the coming Premier League campaign.
Mooy has also put pen to paper on a new contract with the Terriers, who were relegated from the top flight last term, and Huddersfield have the option to extend his deal by a further 12 months.
"We are delighted to welcome Aaron to the club. He has played very well over the past two seasons in the Premier League and will bring a different option and added competition to our midfield," Brighton boss Graham Potter told the club's official website.
"He's been a talisman for Huddersfield in recent seasons with his performances on the field and he's proved to be an excellent professional both on and off the pitch.
"I'm looking forward to working with him and he is another good addition to our squad ahead of the new season."
Mooy has spent the past three seasons with Huddersfield, helping the club win promotion to the Premier League in the 2016-17 campaign.
