For the 1997–98 season, Hann reached the televised stages of more tournaments, lasting until the second-rounds of the Grand Prix (where he set a record of 13 consecutive victories with a 5–4 margin and compiled the highest break of his career, a 141), the UK Championship, and the German Open tournaments. He lost in the first round of the preliminary stages of the British Open with a 5–0 whitewash to Drew Henry in April 1998. One month earlier, Hann became the first Australian player since Eddie Charlton in 1992 to qualify for the World Snooker Championship. He was eliminated by Mark Williams 9–10 in the first round, ending the season ranked No. 45 in the world.
