A-League expansion club Macarthur FC have lost chief executive Archie Fraser just four months after his appointment.
The club announced on Friday Fraser will finish on September 6 before returning to Melbourne for a role in the technology sector.
Chairman Rabieh Krayem will fill in the role until a replacement can be found.
The Bulls are set to enter the A-League in the 2020-21 season and have already announced Matildas coach Ante Milicic will be their inaugural coach.
Milicic's appointment was confirmed in May and he'll take over after next year's Tokyo Olympics when his national team contract expires.
The club will play at a refurbished Campbelltown Stadium in Sydney's western suburbs.
