How do I dial mobiles vs landlines in Christmas Island

Christmas Island uses Australia’s numbering plan. For landlines from abroad, dial your exit code → 61 → 8 → 9164 → the last 4 digits (example: +61 8 9164 8300). Inside Australia (including the island), dial 08 9164 XXXX. International calls placed from Christmas Island use Australia’s international prefix 0011 (e.g., 0011 + country code + number).

Mobiles vs landlines: Mobiles use standard Australian mobile ranges, no island-specific mobile prefix—domestically they start 04…, and internationally they’re +61 4… (drop the leading 0). On-island radio access is provided by Telstra (4G service); roaming works only if your carrier has a roaming agreement with Telstra. Coverage is mainly around the settled areas; check Telstra’s map if you’ll be outside town.

Which mobile prefixes do mobile operators use in Christmas Island

Dialing tip: Converting a Christmas Island mobile is the same as anywhere in Australia: 04… → +61 4…. From the island to overseas, dial 0011 + country code + number; from overseas to the island, dial +61 8 9164 XXXX
