For teens craving “one stamp isn’t enough,” multi-country routes link New Zealand’s adventure circuit with Australia’s Great Barrier Reef and Fiji’s island villages. Picture this: zorbing in Rotorua on Monday, scuba certification in Cairns by Friday, then village homestays and a sunset kava ceremony the following week. Some programs offer flexible departures—students pressed for time can peel off after New Zealand and Australia, while others continue to Fiji for the grand finale.
