The Gold Coast Whale Watching Tour May-November is the best season for whale watching in Australia. Thousands of whales migrated along the coastline, from Antarctica to the north to the warm waters of the Australian coast to breed offspring, and return to Antarctic waters in the spring of next year. The Gold Coast of Queensland, Australia, is one of Australia's best whale watching locations. I am a half-day tour on Trip, every day from 7 in the morning.
