ArchiMate Modelling for WA Government Entity

The project requires using ArchiMate to model a chosen Western Australian government service (from https://www.wa.gov.au/services). The model should cover the business, application, and technology layers. While not needing 100% detail, it should include major services and functions. The modeler can use information from the website, personal experiences, and make assumptions where needed. Explanations for certain business functions or processes can be included, but a detailed service explanation isn't required.
