did the christmas islands get hit by boxer day tsunami

Unfortunately, yes. The Christmas Islands were affected by the Boxing Day Tsunami of 2004, which caused extensive damage and loss of life. Many areas of the islands were flooded, including the port town of Flying Fish Cove, which suffered extensive damage. The tsunami also caused landslides and other damage to the island's infrastructure. The islands have since rebuilt and recovered from the disaster, but the memory of that tragic event remains.
