Hi guys. i have same issue and just stucked with one thing.. Did you "certify" that SelfStatutory somehow? i.e. by public notary or person from this list: https://www.ag.gov.au/Publications/Pages/Statutorydeclarationsignatorylist.aspx??
OR just wrote that + supported with documents [i have self emploment] (which makes more sens in my opinion) and then sent to ACS.
can you help?
thx
Alex
