What are the requirements and process for renewing an O-A visa at the Sydney consulate?

Has anyone gotten an O-A from the Sydney consulate recently? Going back there later this year for a holiday and will take the opportunity to renew my partner's O-A. Already in the "second year" of the O-A.

Can I use the show funds in a Thai bank account to meet the financial requirements and have a health certificate from a doctor in Bangkok?

Where should I do a police check? Bangkok or Australia?

Do the copies of the documents need to be notorised and bound (Canberra website says yes, Sydney is silent), and how long has the process taken for you?

Tried emailing the Sydney consulate but they haven't been responsive. I would like to avoid sending the passport to Canberra (risk of loss, time etc).

Thanks in advance.
