Mulvey appointed to Malaysia post
Mulvey, 52, was sensationally sacked by Roar in November just months after leading the club to the 2013-14 premiership-championship double.
Speaking of his new position, the Manchester-born coach told the Brisbane Times: "It's not often you get given an opportunity where you can give back to football in our region – which they most certainly are – and this was something I may not get to do again.
"I feel like it's a project where I can come in, work with the local coaches and players and provide them with some of the knowledge and insight from the A-League level, giving them something to work with going forward.
"Sabah is a rich football region and while they've had some success in the past, they realised the need for some assistance to steer the club back on track."
Mulvey admitted he took some convincing to take up the job.
"They came back to me again and again and eventually the region's sports minister asked me to get involved,” he said.
"I could see their passion and vision was very much about restoring their club to what it was in the mid-1990s (winners of the Malaysian Super League in 1995 and Malaysian FA Cup in 1996).
"Other clubs are spending huge amounts to get ahead in Malaysia but I think we can find an edge in terms of preparation, performance and professionalism."
