How is a coach selected?
Selection of coaches for International tournaments is up to each team (or parent if individual coaching is desired).
Having a coach, while recommended, is not mandatory.
Internet access is sometimes unpredictable at various tournament locations and time zone differences can make internet coaching problematic. It can, however, be an option for individuals.
Flights, accommodation and tuition for a private coach is prohibitively expensive so it is recommended that the team consider selecting a team coach. Australia has often chosen an Australian-connected coach from the host country (or a nearby country), dramatically reducing travel costs for the coach.
If a team coach is selected you do not have to participate. It is advisable to get clear agreement from everybody before making a final selection.
Some events provide free accommodation for one team coach. If multiple coaches are coming then the financial benefit of free accommodation should be distributed to each coach on the basis of number of students. For example in the scenario where there are 6 players, 1 coach for 4 of them, one player has their own coach and another uncoached then the coach with 4 students will be attributed with 80% of the financial benefit, the coach with one player with 20% and the uncoached player no financial benefit from the free accommodation.
