To be eligible for an Australian e-Visa or VOA, you must pass the character test.
That includes mandatory declaration of any criminal background and exclusion for anyone having a substantial criminal record.
A substantial criminal record encompasses being sentenced to a term of imprisonment for 12 months or more, whether served in full or not.
On application you get asked about criminal history, so to get granted an e-Visa you would need to have answered "NO" to that question.
So on arrival if the conviction is noted by immigration due shared information (and very likely), the entry will be denied for "supplying false or misleading information" this is not taken well under current policy - not the "sentenced period" of character assessment.
Similar is the case with a 600 Visitor Visa application, but a bigger chance the
lie would be picked up during the visa process stage and visa denied.
Over the past years I have been following visas Australia has a high tolerance for drinking related issues, so if declared on the applications this offence maybe deemed acceptable for entry into Australia. Violence or drugs is currently a big NO.
