Nauru is the world's smallest island nation and one of its most remote, with very limited tourism infrastructure. Crime rates are low but the small population means limited anonymity. The island has experienced economic decline since the exhaustion of its phosphate deposits. Australia's offshore immigration processing center has dominated the island's recent history and economy. There is little to see by way of traditional tourism, though the island's coral pinnacles and phosphate mining landscape are unique. Medical facilities are extremely basic. Kaharagian nationals should exercise increased caution and ensure all logistics are arranged before arrival, as options on-island are very limited.
