Meaning
The flag of Christmas Island, an Australian territory in the Indian Ocean. It is divided diagonally into blue and green, with the Southern Cross, a golden bird and a yellow disc showing the island’s shape.
The island is best known for its yearly red crab migration, when vast numbers of crabs march to the sea, so the flag often appears with 🦀. It is also handy for holiday puns: “Spending the holidays on the actual Christmas Island 🇨🇽🦀”
