The 34-year old ex-Rangers championship winner spent two years in the Australian competition before returning to Scotland where he is now enjoying his role as coach and mentor to disadvantaged kids with council-backed initiative 'aplusmtraining.com'.
Miller is still looking to continue his playing career but admits for the time being he is happy working with ex-Dundee United teammate Andy McLaren to get youths involved in football and away from the drink, the drugs and the fights.
"I've been training with Queen of the South and helping Andy with the coaching. I'm loving that aspect. Basically, we're getting kids off the street to train on a Friday night," he told the Daily Record.
"We started a league about four weeks ago. We take teams from around Glasgow, places like Possil, Drumchapel and Yoker. We're getting them off the street away from the drink and it's been really positive.
"They go from aged 11 to 18 so don't really know who I am. I feel I can tell them about the mistakes I made. In fact, with me and Andy you couldn't get a better two."
Miller admitted his playing career had flashed before his eyes and believes coaching could very well be the next step for him.
"When I was young people told me being a footballer is a short career. I thought they were just saying that because they were 30-plus. But they were right, it does fly in," he added.
"I don't remember listening to half of them but I've worked under a lot of good coaches - Norwegians, Belgians, Australians and an Israeli.
"I'd like to become a coach. I feel as if I could help people and I think I know a bit about football."
