Once you are labelled a felon, you cannot stand for parliament. Many jobs are permanently closed to you. You certainly won't be working in aviation or aviating either because by definition a convicted felon is not a fit and proper person to hold a licence.
Neither the term nor the concept of a "felon" is used in Australia.
The only restriction on standing for election related to crime is that you can't be *currently serving* a prison term of longer than 12 months.
No one can be not a fit and proper person "by definition" because there is no written definition. Certainly there is no definition that says someone with a criminal record cannot hold a license. I agree that someone who has been convicted of reckless flying may not be considered fit and proper, but surely that is obvious.
