This guide walks through every realistic pathway for migrating to Australia as an Engineering Professional NEC under ANZSCO 233999. 233999 is a residual ("not elsewhere classified") code on the ROL only. Only Subclass 494 is open. Subclass 189, Subclass 190, Subclass 491, Subclass 186, and Subclass 482 are NOT open.
For the assessing-authority detail, see the 233999 skills assessment guide. For worked numbers, see the 233999 cost & timeline case study.

What ANZSCO 233999 covers (residual code)
- Cross-disciplinary engineers that don't fit a single defined discipline
- Speciality engineers like fire engineering, acoustics engineering (where not 233xxx), nuclear engineering, energy efficiency engineering
- Robotics / autonomous systems engineers (where not fitting 233513 Mechatronics)
- Pure cost / project / project controls engineers (where not fitting 233213 QS)
Strategic alternatives — strongly consider before lodging
| Approach | Visa pathways open | Best for... |
|---|---|---|
| 233999 (Engineering NEC) | 494 only | True residual fit only |
| 233111 / 233112 / 233211 / 233214 / 233215 / 233311 / 233411 / 233512 / 233513 / 233611 / 233612 / 233911 / 233912 / 233913 / 233914 / 233915 / 233916 | Full visa stack incl 189 | Discipline-specific engineering |
Pathway — Subclass 494 → 191
494 is regional employer-sponsored provisional. Realistic 494 employers:
- Tier-1 EPCM — Worley, Aurecon, GHD, Wood, Jacobs, AECOM
- Defence specialty — BAE, Lockheed Martin, Northrop Grumman (specialty engineering)
- Speciality consultancies — Norman Disney & Young (fire), Aurecon Acoustics, Renzo Tonin (acoustics)
- Nuclear / radiation — ANSTO (Australian Nuclear Science and Technology Organisation), defence nuclear (AUKUS)
Common mistakes that cost engineers their assessment
Defaulting to 233999 when discipline-specific code fits. Code-fit determines visa pathway access dramatically.
Treating residual codes as "easier". They're not. Tighter scrutiny + far narrower visa access.
