Yes, and I believe all refs would hold day jobs away from the game. So that becomes very hard if you have to hop on a plane to Buenos Aires or Joburg every few weeks.
Can't confirm for all refs, but ref is a full time job for most. Talked to Jaco Peyper after he reffed the Rebels v Crusaders game in Melbourne when Mortlock scored the winning try. He was telling me he spends his week in the gym working on fitness and even will spend time running with teams at training as it's how he manages to get extra match conditions practice.
