In May 2013, Robertson made the second official maximum break of his career in the Wuxi Classic qualifiers against Mohamed Khairy. In the main stage of the tournament, he defeated John Higgins 10–7 in the final to secure his eighth ranking event title. He came from 2–5 down against Higgins to lead 8–5 before withstanding a fightback to complete the victory and ensure his second consecutive ranking event win in China. In his home tournament, the Australian Goldfields Open, he made it past the second round for the first time in the three stagings of the event, before continuing his run by beating Joe Perry 5–2 in the quarter-finals and Mark Selby 6–3 in the semis. He would have become the first man since Ronnie O'Sullivan in 2003 to win back to back ranking events in the same season, but he lost 6–9 to Hong Kong's Marco Fu in the final. On 8 December 2013, Robertson defeated Mark Selby 10–7 in the final of the UK Championship, becoming the first overseas player to win all Triple Crown events.
