To the OP; I've been through the process and it's as follows:
If you have ever been arrested (for crimes of moral turpitude) you MUST declare it to the US consulate.
Theft is moral turpitude.
By their laws, any arrest constitutes an immigration conviction. It does not matter what the court outcome was by Australian law, if you were officially arrested, you need to apply for a visa.
Get a Police record that displays the individual charges and outcomes. A Victorian Police VISA record does not disclose the outcome of non-(criminal) convictions. You need a personal record for the US consulate.
You will most likely be denied a visa due to criminal history.
You then apply for a waiver, which takes many weeks and they hold your passport during this time.
If your arrests were only minor and no criminal convictions exist, you have good chances of being granted a waiver.
If you get a waiver, you get a temporary visa (up to 12 months).
For each new trip into or over the US, repeat all the steps above.
More information can be found here, if you wade through the legal jargon.
That's 100% correct zetski! Out of curiousity, is the USA the only country that requires you to get a personal record? I'm pretty sure it is. Do you know if Canada requires just a visa check or do they also require a personal record?
From my experience, when you call up to book a fingerprint check they ask you if it's for a U.S visa, so I presume they would only do personal checks for the U.S.A and all other countries you would just need a visa check.
