For interest I emailed Aviation ID Australia 4-5 weeks ago to confirm, as per their website, it appears the only people who can certify documents are pretty well JoP's whilst through CASA can be a whole lot more - including the local postmaster who did my passport 6 months ago.
I am assuming they received my email (didn't bounce back) but no reply.
Regardless of pricing differences (which seems to have narrowed in the last few months) to a similar cost, having looked at local JoP's it's all to hard to find one; on that basis alone I'll do mine through CASA and certified by my local postmaster.
By no means commenting on the efficiency (or otherwise) of any one organisation, just commenting on it seems far easier/more options to certify the paper trail with CASA.
If I have mistaken/missed something regarding Aviation ID Australia certainly would appreciate info.
Cheers
