After long time, the new rule is coming to effect. This is common sense that driving instructor works with children under 18 and they must be part of the check. Hard to believe why it took so long. Anyway, now parents will be able to check if their driving instructor has the clearance to teach driving their children. They will feel better definitely.
Parents or any other individual can verify Working with children check in this link. https://www.kidsguardian.nsw.gov.au/working-with-children/working-with-children-check/apply/apply
Every instructor will have a working with children number. Parents will need Name, date of birth and children check number to verify their clearance.
As of today, 1/7/2016, any instructor applying to renew their licence will be required to provide their WWCC number and expiry date to RMS and New instructor licence application must have a WWCC number to be approved.
From 1/4/2017, there will be no instructor without any working with children check number in the industry. I believe this new rule will have some positive effect in the industry.
