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 Diesel Motor Mechanic 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

A positive skills assessment for Diesel Motor Mechanic comes from:

What the assessment actually involves

Diesel Motor Mechanic sits in ANZSCO unit group 3212 Motor Mechanics alongside Motor Mechanic (General), Motorcycle Mechanic and Small Engine Mechanic, sharing the group's full MLTSSL/CSOL, eight-visa spread. ABS's own group description notes that "parts/accessories fitters" are excluded from this unit group and belong elsewhere — a boundary worth checking against, since diesel-specific parts and accessories work can sit close to that line. TRA's own criteria distinguishing diesel-specific evidence from general motor-mechanic evidence could not be verified in this research, as its website did not resolve.

Where these applications come unstuck

The confusable-code risk for this occupation runs against the general unit-group exclusion ABS states rather than against a specific sibling code: work that is really parts- or accessories-fitting, rather than diesel engine repair and maintenance itself, does not belong in unit group 3212 at all. This research did not find state-level licensing or registration requirements specific to diesel motor mechanic work — the state licensing evidence gathered for this family concentrated on electrical and plumbing trades and did not extend to motor trades.

An honest read on this pathway

Diesel Motor Mechanic shares the full eight-visa spread with the rest of unit group 3212, so the visa-list position is strong and identical to Motor Mechanic (General). Whether this occupation carries any state-based licensing or registration requirement beyond a TRA skills assessment was not confirmed in this research — treat that as an open question rather than an assumption either way, and check directly with the relevant state motor-trades or consumer-affairs regulator before assuming a skills assessment alone is sufficient.
