In which year was the International Rogaining Federation founded in Melbourne, Australia?

International Rogaining Federation (IRF) is the peak international body for the sport of rogaining. The aims of the IRF are to promote rogaining worldwide, maintain the culture and the rules of the sport. It was established on June 16, 1989. The IRF is registered and based in Melbourne, Australia.

Rogaining is an orienteering sport of long distance cross-country navigation, involving both route planning and navigation between checkpoints using a variety of map types. In a rogaine, teams of two to five people choose which checkpoints to visit within a time limit with the intent of maximising their score. Teamwork, endurance, competition and an appreciation for the natural environment are features of the sport. Championship rogaines are 24 hours long, but rogaines can be as short as two hours.
