In Queensland drink driving is considered a "simple offence" or "summary offence" that can be summarily be dealt with by a magistrate.
An "indictable offence" either a crime or misdemeanor, must be prosecuted on an indictment before a judge and jury in the District or Supreme Court.
I have been advised that a conviction for a summary offence is not usually considered for ASIC and other checks. Nor for most foreign Visa's, with Canada being a exception I believe.
Convictions for an indictable offence will be considered for ASIC and some other police checks.
At our company you must fill out a questionnaire, and I have seen on occasion certain charter customers have specified no crew with criminal convictions including drink driving. The operable word being "convictions".
