Get an asic application, its all detailed on that.
I myself have an indiscretion some 12 - 13 yrs ago which still comes up every asic renewal. They still issue the card but you must be upfront about it evry time you renew the card or they think your trying to hide it away, even though they say the nature of the incident does not warrant listing it on the application.
Any questions, ring the feds in canberra.
