Christmas Island, an Australian territory in the Indian Ocean, is a remote speck known for its annual red crab migration, where millions scuttle from forest to sea. Its tropical landscape hosts unique biodiversity, including rainforests and coral reefs, drawing eco-tourists. The island’s population, centered in Flying Fish Cove, reflects a mix of Chinese, Malay, and European heritage from its phosphate mining past. Though small, its isolation and natural wonders make it a standout ecological gem.
