Christmas Island Domain Administration (cxDA) is a not-for-profit, industry self-regulatory entity controlled by its members. cxDA was established in 2000 to oversee the Christmas Island top level domain on behalf of the Christmas Island community. cxDA's principle purposes are:

  • to be the administrator of the .cx ccTLD;
  • to maintain and promote the operational stability and utility of the .cx ccTLD and more generally, the Internet's unique identifier system, and to enhance the benefits of the Internet to the Christmas Island community;
  • to ensure the cost-effective administration of the .cx ccTLD;
  • to administer the .cx ccTLD including:
    • i. rules governing acceptable use of the cx ccTLD;
    • ii. rules governing the accreditation of registrars and registry operator;
    • iii. rules governing the registration of names;
    • iv. rules ensuring that registrars have equal access to registry services.
  • to exercise oversight of the operation of critical technical functions including:
    • i. the primary and secondary .cx name servers;
    • ii. a searchable database containing current and historical information on registrations within the.cx ccTLD.
  • to liaise with national and international bodies on issues relating to the development and administration of the domain name system.
  • to establish appropriate complaints handling and dispute resolution processes to provide for conciliation or redress of grievances on matters associated with use of .cx domains or the administration of the .cx ccTLD.

The cx TLD is a small ccTLD - 14,000 domains.

It is not possible to register domains through CXDA, under the "three r model" ( Registry, Registrar, Registrant ), domains must be registered through a registrar.

cx TLD Policy

Policy for the CX ccTLD has been drafted to:

  • ensure the use of domains ending with the two-letter suffix .cx is consistent with the culture and customs of the Christmas Island community and applicable Australian law and public policy objectives.
  • ensure the application of a "three R" model (registrant, registrar, registry) which facilitates competition and safeguards consumer interests.
  • mitigate abuse of the cxDA namespace, serious harms to consumers are/can be resolved swiftly directly by cxDA without the requirement to contact registrars.

cxDA a strong commitment to domain abuse prevention:

  • cxDA uses the CoCCA Complaint resolution service (CRS) which provides a transparent, efficient and cost effective way for the public, law enforcement, regulatory bodies, and intellectual property owners to have their concerns regarding use of the .cx name space addressed.
  • CoCCA contracts a former ICANN Ombudsman to do amicable complaint resolution and NZ Experts for binding arbitration. Serious time sensitive harms which violate the cxDA AUP - incitement of violence, publication of prohibited content etc., can be dealt with by cxDA directly.
  • cxDA has been a member of the IWF (Internet Watch Foundation) the company that works to eliminate online child sexual abuse imagery since 2016.

Any party who believes a domain name registrant has violated the cxDA AUP must provide a formal complaint in order for CoCCA to investigate and evaluate the claims.

Complaint Form

If you have an urgent complaint regarding the distribution of child abuse images please lodge a complaint with both law enforecment and the Internet Watch Foundation. The IWF and/or Law enforcement who will confirm the issue and notify CoCCA for possible action.

In cases where CoCCA has a technical or legal capacity, we will act swiftly on an IWF notice without the need for a formal complaint using the CRS above.

  • any entity who wishes to manage a portfolio of domains on behalf of end-users (registrants) is eligible to be a registrar.
  • there are no fees to become a registrar and no minimum number of domains that must be managed. However, to reward those who actively promote the cx TLD, wholesale pricing is based on volume. The more domains under management the lower the registry fees.
  • pre-payment for registry transactions is required, formal accreditation agreements are optional.
  • the wholesale registration and renewal fees are set by the registry services provider (CoCCA). The cxDA fee is included in the wholesale registration and renewal price.
  • the retail registration and renewal fees are set by the registrar or reseller.

** Minimum fee. Can be increased by cxDA as required to meet expenses. cxDA operates on a non-profit, cost-recovery basis.


cxDA uses shared registry instances/infrastructure managed by CoCCA for economies of scale. In addition to Christmas and Norfolk islands, the shared registry infrastructure used by cxDA hosts the ccTLDs for Afghanistan, Chad, Greenland, Ivory Coast, Timor- Leste, Honduras, Haiti, Kirabatti, Saint Kits, Solomon Islands, Somalia and Zambia.


cxDA seeks to apply the core principles of good corporate governance; fairness, accountability, responsibility and transparency. Membership is open, policy input is welcome from entities inside and outside the local community.

The day-to-day technical operation of the registry has been outsourced to CoCCA Registry Services (NZ) Limited. The cxDA-CoCCA Registry Agreement is based on the ICANN TLD agreements. The term is 10 years and expires in 2026.

CoCCA collects a minimum of AUD $1.75 from each registration or renewal transaction on behalf of cxDA. Under the the current outsource agreement, the transaction fee payable to cxDA can be increased to ensure cxDA remains solvent. The fee was initially based on the auDA-AusRegistry fee in place in 2016, when the agreement was signed. It has been/is increased periodically as required.

Since cxDA ceased operations as the Christmas Island ISP, the transactoin fee is cxDA's sole source of revenue. The modest revenue is sufficient to cover expenses related to legal/auditing, monitoring abuse, and maintaining the community email service. cxDA officers are volunteers and receive no compensation.

cxDA accounts are open to any interested party. cxDA uses Cornerstone Partners in Perth for accounting services and William Buck as the auditors.

*For 17 years, starting from 2000, cxDA operated a member-owned ISP (the only ISP in the territory). cxDA did so reluctantly after the only ISP in the territory, a private entity, decided the ISP did not have a viable commercial model. cxDA ceased operating an ISP once a subsidised Australian government service became available. The majority of revenue in the cxDA financial statements prior to 2018 comes from ISP operations.
