, you need to remember that outside of thailand visas are sold at consulates and embassies run under the Ministry of Foreign Affairs Office and inside thailand visas and extensions are sold by the thai immigrations offices which are run by the Royal Thai Police. I doubt those two offices have EVER communicated.
If all you're doing is buying a 90 day Non-O visa from a thai consulate in Australia you can have the money in your account there.
Don't trust the consulate AT ALL as far as how you get an extension of stay on that visa once you get here. There is a good chance that they don't know anything about it.
Now IF you're comin' to thailand on a 90 day Non-O visa and then going to apply for a yearly extension it doesn't matter where the money in your thai bank account comes from because for extensions there is no requirement that the money come from abroad. The only requirement is that it is a thai bank account in your name for 60 days prior to you applying for the yearly extension.
