OSCA 2024

The Occupation Standard Classification for Australia (OSCA) 2024 is the latest standardised framework for storing, organising and reporting occupation-related information. OSCA 2024 replaced the Australian and New Zealand Standard Classification of Occupations (ANZSCO) 2022 in Australia. 

Over 300 new occupations were added to the classification, while almost 250 occupations were retired. 

The updated classification introduces several key features and benefits. These include:

• an improved hierarchical structure with better statistical balance, increased granularity and better skill specialisation alignment 
• main tasks added to all occupations providing a clearer and more detailed description of what each occupation involves
• improved visibility of Aboriginal and Torres Strait Islander specific occupations and specialisations
• removal of gendered language to promote gender inclusivity and help eliminate unconscious bias
• incorporation of user feedback to ensure the classification meets the needs of stakeholders. 

Summary of major changes highlights the main changes between OSCA 2024 and versions of ANZSCO, with a focus on reclassification and updates at the group level.

Data downloads are available to facilitate analysis and mapping of the OSCA classification with the International Standard Classification of Occupations (ISCO), Stats NZ's National Occupation List (NOL) and ANZSCO. 

The ABS provides two ways for coding occupation information to OSCA 2024: 

• the Whole of Australian Government Occupation Coding Service (the Coding Service)
• the OSCA Coder
