Hi @davos - technically its not called stat dec pag hindi Au citizen/PR ang pumirma..
<i>"If you are outside Australia and are unable to get an Australian citizen or Australian permanent resident to complete a statutory declaration, Such statements are not statutory declarations under Australian law. However, in accordance with policy, they should be witnessed or certified according to the legal practices of the relevant country."</i>
Here is a link for your info, if you want to use the form:

However, for skills assessment purpose, pwede na ang COE with detailed job description na printed sa blank paper, mas mabuti kung meron kayong company letterhead.. then sign ng supervisor mo, get a copy of his/her ID, or passport kung mas okay.. then have it Notarised..
