How TGA's occupation reached this entity

training.gov.au identifies occupations by its own surrogate key. Reaching an ABS occupation requires a scored, human-reviewed correspondence to ANZSCO 2022 and then ABS's published correspondence to OSCA 2024. Rejected candidates are kept: they are what this entity is not.
