ANZSCO 233512 or OSCA 243532?
The Australian Bureau of Statistics released OSCA in December 2024 to replace ANZSCO for statistics. The migration system has not switched yet. The Department of Home Affairs still lists skilled occupations by ANZSCO code: the 2013 version for points-tested visas such as the 189, 190 and 491, and the 2022 version for the 482 and 186 employer-sponsored visas.
For your skills assessment and visa application, use ANZSCO 233512. In OSCA it sits in unit group 2435 Industrial, Mechanical and Production Engineering Professionals, alongside Industrial Engineer and Production or Plant Engineer.
Visa Options for Mechanical Engineers
Mechanical Engineer (233512) is on the MLTSSL and the Core Skills Occupation List (CSOL), subject to each visa’s own requirements:
Lists change, so check the Home Affairs skilled occupation list before you lodge.
Engineers Australia Skills Assessment
If your mechanical engineering degree is not accredited in Australia or covered by the Washington Accord, Engineers Australia assesses you through a Competency Demonstration Report (CDR):
- Three career episodes, each about your own engineering work, with numbered paragraphs
- A summary statement mapping all 16 elements of competency to paragraphs in your episodes
- A CPD statement listing your continuing professional development
The CDR assessment fee is AU$1,034 including GST. Standard applications wait around 15 weeks to be assigned to an assessor; fast track (an extra AU$396) assigns your application within 20 business days.
The English scores above are the minimum in each component for tests taken on or after 7 August 2025. Cambridge C1 Advanced, LanguageCert Academic, Michigan English Test and CELPIP General are also accepted. You are usually exempt with a UK, US, Canadian, New Zealand or Irish passport, or after two years of study in Australia.
What a Strong Mechanical Engineer CDR Shows
Assessors want to see your own engineering judgement, not your team’s work or your job description. Strong mechanical career episodes include:
- Design and analysis you did yourself: stress, fatigue, heat transfer or fluid flow calculations, with your software (for example SolidWorks, AutoCAD, ANSYS or MATLAB)
- The standards you applied, named specifically (for example ASME, ISO or your national code)
- A real problem you solved, such as a failure analysis or root cause investigation, and how you checked your solution
- Project and plant work: commissioning, testing, maintenance planning, safety and cost control
Common reasons mechanical CDRs fail: writing “we” instead of “I”, routine maintenance with no engineering analysis, copying a job description, and summary statements that point to the wrong paragraphs.
Which Mechanical or Industrial Code Fits You?
Choose the occupation that matches what you actually do most of the time; your career episodes must support it. Under ANZSCO, mechatronics engineers are listed under Engineering Professionals nec 233999.
Frequently Asked Questions
What is the ANZSCO code for a mechanical engineer?
233512. In the newer OSCA classification it is 243532, but visa applications still use the ANZSCO code.
Is mechanical engineer on Australia’s skilled occupation list?
Yes. Mechanical Engineer (233512) is on the MLTSSL and the Core Skills Occupation List (CSOL). Always check the current Home Affairs list before you apply.
Who assesses mechanical engineers for Australian migration?
Engineers Australia.
Do mechanical engineers need a CDR?
Yes, if your degree is not accredited in Australia or recognised under the Washington Accord. The CDR has three career episodes, a summary statement and a CPD statement.
What is OSCA 243532?
The code for Mechanical Engineer in the Occupation Standard Classification for Australia, released by the ABS in December 2024. It replaced ANZSCO for statistics; migration still uses ANZSCO.
How much does the assessment cost and how long does it take?
AU$1,034 including GST. Standard applications wait around 15 weeks for an assessor; fast track (an extra AU$396) within 20 business days.
