The next few seasons were anticlimactic, Dunn's best progress being a run to the semi-final of the non-ranking Benson &amp; Hedges Championship, where he lost 3–6 to Mehmet Husnu; however, 2005 heralded a first-ever last-16 finish, at the 2005 Malta Cup. There, he beat Leo Fernandez, Michael Judge, Marco Fu, local wilcard entry Simon Zammit and David Gray - whitewashing the latter 5–0 - before losing 3–5, again to Stevens.
