Miah's Q School Order of Merit gave him entry into the 2015 Australian Goldfields Open qualifiers in which he began with a century break and won his first ranking event match in almost a year by beating Jason Weston 5–2. He lost 1–5 to Anthony Hamilton in the subsequent round. He was eliminated in the third round of three European Tour events during the season, which included scoring 4–3 wins over Mark Davis and Judd Trump. This saw him finish 60th on the Order of Merit to secure a new two-year tour card starting next season.
