Processing priority
Diesel Motor Mechanic isn't in any of the ANZSCO groups that Directions 121 and 122 list for the priority sectors. Some of the first group is defined by the job rather than the code: a nominated position directly involved in agriculture, aquaculture or fishing, one that directly supports mining, oil and gas or coal production, or one related to defence. Otherwise the application is processed after the priority sectors. For the permanent and provisional skilled visas, applicants who were in Australia when they applied come next, then those who applied from outside Australia. For the 482, Specialist Skills stream applications come before both.
Priority changes the order in which lodged applications are looked at, not whether they are granted. Who is invited to apply through SkillSelect is decided separately. See all 202 occupations in the priority sectors.
Skills assessment
A positive skills assessment for Diesel Motor Mechanic comes from:
- Trades Recognition Australia (TRA) (official site) · our guide to the TRA process
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.
