Johanna Allston, or Hanny Allston, as it is called by many, lives in Tasmania, where she studied medicine and part-time working as a guide for bushwalking. In her youth, she operated mainly swimming. However, a shoulder injury forced her to quit so she switched to orienteering. Allston also keen to take on other endurance sports competitions such as ultra-marathons, triathlons, cycling or kayaking competitions.
Hanny Allston won the long distance of the Junior World Orienteering Championships ( JWOC ) in Lithuania in 2006. The residue of the second-placed runner was significant 4 minutes 38 seconds. It is thus the first Australian runner who has ever won a gold medal at world championship level. But the triumph at the JWOC should not be the highlight of their most successful season. Inspired by the very good performance, the Australian joined the 2006 World Championships in Denmark at all distances and was able to sprint gold medal and thus secure the world title. It is thus the youngest and first world champion from Australia.
At the 2009 World Games, she won the race over the middle distance and was second in the sprint.
