Born on 16 August 1977, Dallas was a carpenter prior to an accident in 2000 where he broke his back after falling through a roof. He also used to be a surfie. When he was young, he moved around a lot. After finishing his HSC, he moved to Toongabbie where he lived with a friend in a loungeroom. Dallas is from Terrigal, New South Wales. He moved there in around 2003. Dallas does work as a public speaker. In 2010, he spoke at the Concord Library about his experiences with disability sport. That same year, he also spoke at Delfin Lend Lease about workplace safety. In 2009 and 2010, Dallas worked in wheelchair basketball development on New South Wales's central coast. He also worked as a newspaper columnist. In 2010, he played wheelchair basketball for the Sydney University Wheelkings. He had four relationships in four years in the lead up to the 2010 Winter Paralympics. The demands of high level skiing was a factor in the relationships not working. In 2009, he had a shoulder reconstruction, and other rehabilitation at the Mount Wilga Rehabilitation Hospital. He also dealt with necrotising fasciitis, a flesh-eating bug, that sidelined him for seven months. The flesh-eating bug treatment involved a skin graft. Dallas was featured on the Australian Broadcasting Corporation's X Paralympic Games in March 2010.

In 2007, Dallas won a World Cup. In 2009, he won the World Championships for the super-G. He had a high speed crash at the 2009 IPC Alpine Skiing World Championships in Korea in the downhill event, which resulted in severe injuries that doctors thought might end his career. Dallas was officially named to the Australian 2010 Winter Paralympics team in November 2009. A ceremony was held in Canberra with Australian Paralympic Committee president Greg Hartung and Minister for SportKate Ellis making the announcement. He and the rest of Australia's para-alpine team arrived in the Paralympic village on 9 March 2010. At the Games, he competed in the super-G event, when he was the super-G world champion at the time. In the super-G, he finished 12th. He also competed in the super combined, downhill and giant slalom events. He did not place in the super combined event as he failed to finish his second run because he crashed. He had been sitting in the sixth spot after his first run and kept sixth spot after his second run. He finished 11th in the super-G. He finished ninth in the super combined. He did not finish in the slalom. He overskied the giant slalom and finished sixth. The giant slalom course was difficult, and Dallas was one of only 30 out of 54 skiers to finish the course. Following the 2010 Winter Olympic Games, Dallas took a break from the sport, and had originally planned as a retirement that he announced before the 2010 Games.
