On the Medium and Long-term Strategic Skills List and Core Skills Occupation List
From the official Home Affairs skilled occupation lists, as at 2026-08-12. Lists change at each government update — always confirm on the official page before acting.
Which lists is Hydrogeologist on?
MLTSSL — Medium and Long-term Strategic Skills List. The widest list — occupations on the MLTSSL can access the points-tested permanent skilled visas including the Skilled Independent visa (subclass 189), which needs no state nomination or employer.
CSOL — Core Skills Occupation List. The employer-sponsorship list — occupations on the CSOL can be nominated for the Skills in Demand visa (subclass 482) and the Employer Nomination Scheme 186.
Visas this occupation can access
Being on a list makes the occupation nominatable for these visas — each visa still has its own requirements (points, age, English, a positive skills assessment, and for sponsored visas a willing employer or state).

Skills assessment

What the assessment actually involves
VETASSESS describes Hydrogeologists as studying the distribution, availability, flow and quality of underground water. Its accepted field-of-study list is broader than most in this family: Hydrogeology or Pure Geology as a major, or — stated directly on its own page — "water resources engineering, environmental science or other related subjects with additional postgraduate studies in hydrogeology from a recognised tertiary institution." That postgraduate-conversion route is a genuine pathway other geo-science occupations in this family were not observed to offer in the same explicit form.
Where these applications come unstuck
Geologist's own page names Hydrogeologist as an explicit exclusion, so groundwater-specific work should not default to the more general Geologist title — that page treats hydrogeology as a separate, excluded specialism. The other detail worth checking closely is the qualification-field route itself: the postgraduate-hydrogeology pathway requires that the postgraduate study specifically be in hydrogeology, from a recognised tertiary institution, not simply a general environmental-science postgraduate qualification loosely adjacent to water resources.
An honest read on this pathway
Hydrogeologist carries MLTSSL and CSOL, reaching all eight visas in this family, the same strong position as Geophysicist and a materially better one than the excluded Geologist code, which sits on STSOL with no 189 or 485. The broader accepted-qualification list — a genuine postgraduate-conversion route for water-resources engineers and environmental scientists — makes this one of the more accessible entry points in the geo cluster for someone without an undergraduate hydrogeology or pure geology degree specifically.
VETASSESS assesses qualifications and employment separately. Both need documentation that agrees with itself. The Employment History Builder and Document Vault organise each trail before you lodge.
