The club announced Behich's move, a loan from Melbourne City until the end of the season, on Wednesday morning, and he will head to the Gulf state once the Socceroos' Asian Cup campaign is over.
"#AlNassr can confirm the signing of Australian national team player Aziz Behich on a loan deal until the end of the season," the club wrote on social media.

The 33-year-old's signing was announced barely an hour after South Korea beat Saudi Arabia on penalties to tee up an Asian Cup quarter-final clash with the Socceroos.
He has started every game of Australia's campaign in Qatar at left-back, pushing young gun Jordy Bos to the wing.
While Ronaldo is the biggest name at Al-Nassr, Behich will also now be teammates with ex-Liverpool forward Sadio Mane, former Manchester City centre-back Aymeric Laporte and Croatia midfielder Marcelo Brozovic.
Behich's move is a shock given he had signed a two-year deal with Melbourne City, his hometown club, until the end of next season, and appeared settled there.
It also overshadowed the A-League Men club's announcement of the signing of former Socceroos midfielder James Jeggo until the end of 2025-26.
Behich had been a regular starter at City, scoring a goal and registering two assists in 19 appearances across all competitions this season.
Elsewhere in the ALM on Wednesday, Adelaide confirmed the immediate sale of defender Alexandar Popovic to South Korean first division side Gangwon FC.
"Alexandar's departure is a testament to the talent we nurture at Adelaide United, and we are proud to have played a role in his development as he takes on an international challenge," said Red boss Carl Veart.Â
