You won't. You can restore an expired licence any time within a year of expiration. Logically, the only reason to renew it is to work it so one can't blame Welfare for cutting your dole. However, when they do that it only takes a phone call to get it back provided your income is significantly impacted by COVID '19. If you have any problems contact Richard Boyd Barrett or your local SPBP representative. From NTA email:
If you cannot renew the licence by this date, you may book a renewal assessment after this date, when you are ready to return to operating your vehicle. Any SPSV vehicle licence holder who is unable to complete a licence renewal due to the COVID-19 pandemic, will not be subject to any ‘late renewal fee’.
