The 28-year old Australian international spent over a year-and-a-half in Japan but has now signed with Al Ain as confirmed on the club's official website.
A club spokesman added on Sport360: "We are delighted to announce the signing of Alex Brosque.
"He fits the bill of exactly what we have been looking for. He is a quality player and has a proven track record in Asian football.
"He creates as well as scores goals and we firmly believe he will be a big asset for the club."
The flexible attacker netted 17 goals during his time with Shimizu and has recently been the Socceroos' main striker under Holger Osieck.
