Australian Government departments and agencies are obliged by the Disability Discrimination Act 1992 to ensure that online information and services are accessible by people with disabilities. There is also the requirement to make online resources accessible to those people with technical constraints, such as older browsers and lower speed Internet connections.

This website aims to conform to Level AA of the Web Content Accessibility Guidelines version 2 (WCAG 2.0), developed by the Web Accessibility Initiative of the World Wide Web Consortium (W3C).

The NPI web site has been developed to display adequately on all commonly used browsers. Special features have been included to enable effective operation by persons using accessibility hardware and/or software. The site is optimised for a 1024 x 768 screen resolution but will scale appropriately to both higher and lower screen resolutions.

For technical reasons and to meet some legal requirements, the NPI web site has a number of documents that cannot be provided in HTML or other alternative formats.
