Probably not.
Your personal convenience is not a factor.
Nor is any wish you may have to keep it a secret from the people around you these days.
In the worst case scenario, you can be arrested in Victoria, by Victorian police,
and extradited to South Australia.
Bail in South Australia is not a given (you are a flight risk).
Understand that "faili to appear" can be a second, separate offence,
for which a further penalty can be imposed.
