Team contributions are different in different countries.
The contribution to join a China team in 2017 is $AUD1150 per person. This includes your land costs once you are met at the airport to when your team has finished. It doesn't include personal snacks or souvenirs or personal travel like taxis to go shopping etc. Neither does it cover the travel expenses getting to China such as flights, visa or any vaccinations you may like to have.
Team contributions in India and Indonesia depend on the team length and activities but so far have been lower than China teams.
