If your visa is cancelled because of your Criminal Record or you otherwise fail the ‘Character Test’, you face a very serious situation.
Unless the cancellation is overturned you will be removed from Australia and will NEVER be able to return for any reason. You will not, for example, be able to return for your mother’s funeral or your child’s 21st birthday.
If you want to stay in Australia, you should get expert advice as soon as you receive a Notice of Intention to Cancel your Visa or, ideally, when you first become aware that you may be in line to obtain a Criminal Record. May be able to successfully argue to a Magistrate or Judge that a non-custodial sentence should be applied to avoid the draconian elements of the Migration Act 1958 s.501.
