The Graduate Diploma in Information Management is a postgraduate qualification at AQF Level 8, designed for professionals who wish to organise, preserve, manage, and provide access to information within a wide range of organisational settings. It bridges traditional information science — encompassing librarianship, archives, and records management — with the demands of the modern digital environment, including data governance, digital preservation, and knowledge management systems. Students develop the skills to design and implement information systems, manage physical and digital collections, ensure regulatory compliance, and support evidence-based decision making across public, private, and not-for-profit sectors. Specialisations are commonly available in library and information management, archives and records management, and information systems, allowing students to tailor their studies to specific career goals.

This qualification is well suited to those entering the information professions for the first time, as well as existing professionals seeking to formalise or extend their expertise. Typical students include recent graduates from humanities, social sciences, law, health, business, or IT backgrounds, as well as working professionals pivoting into information management roles. Employers who hire graduates span a remarkably broad range of industries: federal, state, and local government agencies, national and state libraries, museums and cultural institutions, universities, healthcare organisations, law firms, financial services providers, defence and intelligence agencies, and large corporations managing complex compliance environments. Many programs are accredited by professional bodies including the Australian Library and Information Association (ALIA), Records and Information Management Professionals Australasia (RIMPA), and the Australian Society of Archivists (ASA), ensuring graduates are recognised as qualified professionals upon entry to the workforce.

The minimum academic entry requirement for a Graduate Diploma in Information Management at most Australian universities is a completed bachelor's degree (AQF Level 7) or bachelor honours degree (AQF Level 8), or equivalent, from a recognised higher education institution. Degrees from any discipline are typically accepted — students do not need a prior background in information science, library studies, or IT to be eligible. Some programs additionally accept applicants who hold a completed Graduate Certificate in Information Management (AQF Level 8) with a minimum grade point average, which allows students to 'stack' qualifications in a nested suite of programs. Alternatively, applicants without a bachelor's degree may be considered on the basis of significant relevant work experience — typically a minimum of five years in a related field — combined with demonstrated skills and knowledge equivalent to an AQF Level 7 qualification. Recognition of Prior Learning (RPL), also known as Advanced Standing, is available at most providers and can reduce the total study load required.

For international students and domestic applicants whose previous study was conducted in a language other than English, English language proficiency requirements apply. Most programs require a minimum IELTS Overall score of 6.5, with no individual band below 6.0, or an equivalent score in an accepted alternative test such as TOEFL, PTE Academic, or Cambridge English Advanced. English language test results must generally be no more than two years old at the time of application. Some providers also accept evidence of prior tertiary study conducted entirely in English as a substitute for a formal language test. Prospective students are advised to check each institution's specific requirements carefully, as criteria can vary — particularly for specialised streams in archives, records management, or information technology management.
