ACS documents for Australian Experience - Is JP required?

Hi All,
I had done my ACS in July 2018 from India which doesn’t contain Australian experience. I moved to Australia in January 2019 and by the end of Dec 2019, I completed 1 year in Australia. I was told to submit following documents for ACS to get Australian experience
1] Statutory declaration
2] Onsite work experience document from employer
3] Payslips
4] Bank statements
5] PayG document

I have following queries
1] Please let me know if any docs are missing apart from above ?
2] Do i need to take sign from JP for those documents?

Please suggest.


JP is not mandatory but there is no harm in getting one.

Documents list looks good to me.
