The Integrated Land Information System provides easy access via the internet to a range of information about land and property in the Northern Territory.

The data available covers the cadastre, land titles, land valuations, land use, planning and development assessment, building control, land administration and land acquisitions for Government purposes.

Hyperlinks are used to provide access to an extensive repository of related data such as unit, survey and LTO plans as well as scanned dealings relating to titles.

Accessing the ILIS Application

Non-Government/Internet Clients without a current ILIS Agreement

Non-Government clients can access ILIS over a secure Internet connection with the use of an SSL Certificate installed on the client machine, and a valid user account.  An SSL certificate is provided to clients only after an account has been established 

To request an ILIS Account, an Application for Internet Access and Licence Agreement should be emailed to ILIS Support 

This form is to be used if a non-government client does not currently have a established Agreement, including Government Business Divisions (GBDs) and Statutory Commercial Authorities

After receipt of your application, ILIS Support refers your application to NT Government data custodians, including the Land Titles Office (LTO). A data licence agreement is created by the LTO and sent via post to the applicant to accept, sign and return to the LTO. Please the contact the LTO for further information on (08) 8999 6520.

The Data Licence Agreement governs the use of data provided by the Northern Territory Government. A Data Licence Agreement must be signed by applicants before access is given to Northern Territory data.

Points to Note: Delays can occur due to postage or other unforeseen circumstances, so please allow time for the application to progress.

The LTO can manually provide Land Title and Registered Dealing searches, either over the counter or via fax. If you require a 'one off' document search, an ILIS account may be unnecessary. More information is available at the Land Titles Office website.

Government Users

(including Power Water, Territory Housing, TIO, AVO, Land Development Corporation & Local Government Authorities)

Northern Territory Government employees can access ILIS from within the Government network. Access is restricted to individual needs and is provided on a case by case basis.

Government Users requiring an ILIS Account should complete the NTG ILIS Access form and have it signed by their immediate supervisor.

Forms can be emailed to where they will be forwarded to the relevant ILIS Custodians for their approval. You will receive notification from ILIS Support once your application is complete.

Please note that Government Business Divisions (eg Land Development Corporation, Darwin Port Authority) and Statutory Commercial Authorities (eg Power Water, TIO, LGAs etc) need to establish an Application Agreement at the first instance (see Non-Government Users)
