Hi Experts

Is it a mandatory requirement to upload “certified copies” of the documents for a SC190 visa application.

When I click the “question mark” right next to each “required documents” these are the requirement regarding certified copies

1. Evidence of Birth - Provide a certified copy of your full birth certificate.
2. Evidence of Language Ability - Provide evidence of the applicant's English language ability. This may include a certified copy of score report.
3. Evidence of Overseas Education Qualification - This may include a certified copy of your academic transcripts, educational certificate (degree, diploma etc) or letter/statement from your overseas education institution.
4. Skills Assessment - Provide a certified copy of your skills assessment issued by the relevant skills assessment body.
5. Travel Document – Not Asking for certified copies.
6. Evidence of Work Experience Australian - This may include a certified copy of your employment contract, a letter/statement from your business/employer or work reference.
7. Evidence of Regional Australia Study - Not Asking for certified copies.
8. Evidence of Character History India - Not Asking for certified copies.
9. Evidence of Character History Australia - Not Asking for certified copies.
10. Evidence of Australian Study Requirements - Not Asking for certified copies.

For my application all documents and original color PDFs issued form the issuing authorities like

1. Evidence of Birth – Local Governing Body
2. Evidence of Language Ability – PTE Score Card
3. Evidence of Overseas Education Qualification – University
4. Skills Assessment – Engineers Australia
5. Evidence of Work Experience Australian – Contract Letter from Employer.

So, what does it mean when they ask us to upload a certified copy?

What is the most followed practice related to this
