The Australian Indian Ocean Territories (AIOT or IOT) is an official term used to refer to the two Australian external territories of Christmas Island and the Cocos (Keeling) Islands. The two territories have a common history, both once a part of Singapore, and share a common administrator.

Though the two territories are widely regarded to be in Southeast Asia, both geographically and culturally and even while it's widely regarded that the South Island in the Cocos (Keeling) Islands is the southernmost point of Asia, you'll need an Australian visa to get to the islands, so they have been categorised under Australia for practical purposes.

Regions

Christmas Island Dubbed as Australia's Galapagos Islands, Christmas Island is indeed a true wildlife haven. Whilst it's an island that nearly every Australian would have heard of the island for its annual red crab migration, the island also has impressive forests (most notably The Dales), lookouts, scenery, and a perfect spot for snorkelling.

Cocos (Keeling) Islands A group of coral atolls and islands that have a true tropical setting far flung out, 2,700 km (1,700 mi) northwest of Perth. The islands are mostly comprised of ethnic Malays who were brought as slaves during the 19th century but yet have a very distinct culture of their own, including their own dialect of Malay that drastically differs from the Malay spoken in Malaysia, Singapore or Brunei. As the islands aren't flooded with tourists, you'll find some uninhabited islands with pristine white beaches with low-lying waters surrounded by palm trees – indeed a true tropical paradise that's fairly accessible.

Whilst the Ashmore and Cartier Islands are geographically in the Timor Sea (which is a branch of the Indian Ocean), it is not officially a part of the Australian Indian Ocean Territories, nor is it even considered such. As visiting the two islands require special permits and a matter of sovereignty dispute between Australia and Indonesia, it is not covered in this article. The same goes with the Heard Island and McDonald Islands, but it's not usually considered to be part of the Indian Ocean in Australia.

Towns

There are six settlements in the two territories combined; four in Christmas Island and two in the Cocos (Keeling) Islands. All of them are just tiny towns; with the exception of Flying Fish Cove, they have populations that are no larger than 500 each.

• 1 Bantam – Cocos (Keeling) Islands' largest settlement
• 2 Drumsite – a good place to see the red crab migration on Christmas Island
• 3 Flying Fish Cove (Kampong) – capital and the largest settlement on Christmas Island, where most of the island's Malay population reside
• 4 Poon Saan (Cantonese: 半山) – Christmas Island's second largest settlement whose name literally means "halfway up the hill" in Cantonese where most of the island's Chinese population reside. The town has some great Chinese architecture, and even some streets resemble Cantonese names.
• 5 Silver City – the most Australianised town in the area resulting in a somewhat boring town, but with some good views of the ocean.
• 6 West Island (Cocos Malay: Puluu Panjang; Malay: Pulau Panjang) – the capital of the Cocos (Keeling) Islands

Other destinations

While both Christmas Islands and the Cocos (Keeling) Islands are destinations in their own right, there are many individual places within both territories that are well worth visiting.

• 1 Christmas Island National Park – covers over two-thirds of Christmas Island best known for red crab migration
• 2 Direction Island – a true hidden island paradise
• 3 Pulu Keeling National Park (North Keeling Island; Malay: Taman Negara Pulu Keeling) – a desolate island and Commonwealth Reserve about 50 km north of the main archipelago

Get in

By plane

As of 2023, the only way to get into the territories by plane is by taking a Virgin Australia flight from Perth. While there used to be flights from destinations like Jakarta, Singapore or Kuala Lumpur, these have been indefinitely suspended but there is still that one-off flight that flies ever so often.

The route is somewhat like a triangular loop. Flights usually depart from Perth on Tuesdays and Fridays first northwest to the Cocos (Keeling) Islands, then heads east-southeast to Christmas Island before finally returning back to Perth.

By boat

It might seem like a great adventurous journey from the coast of Indonesia (especially Java) or Western Australia to either one of these islands but it comes with two catches. Firstly, the waters are very rough, which has caused many deaths at sea, particularly closer to the coasts of Christmas Island. Secondly, as these islands are popular among refugees trying to seek asylum in Australia, the navy heavily patrols the surrounding waters, so if you attempt to sail to the islands without following the procedures here, you may be stopped and searched by a navy vessel. Visas must be organised ahead of time and even Australian citizens need their passports.

However, it's still possible and if this doesn't discourage you, follow the procedures listed on the Cocos Islands tourism website if you're sailing to the Cocos (Keeling) Islands or the Christmas Island website if you're sailing to Christmas Island. The council websites for Christmas and the Cocos Keeling Islands may also be of some use.

Go next

Most likely, your only option is to fly back to Perth.
