Somewhere in legislation, yes somewhere amongst the thousands of pieces of law we have, that allows the RTA to release registration information to SYDMacAirport and vice versa, so that any infringements can be suitably sent to the infringing motor vehicle owner. Again there are laws which give authority to private SYDMacAirport parking clowns to issue infringments occuring on intra-airport property & roadways. Vehicle details sent to RTA for action.
There is some financial gain for the RTA / State Governement where they would receive some part of those fines issued. Thus the collections are handled by the State Debt Recovery Office.
This type of partnership also exists for many other agencies such as councils, where councils now employ parking rangers who have authority to issue parking infringement fines for example, the council and state govt share in the infringment money pot. The councils make extra $$$ and the State govt can boast of having more police officers on the beat catching real criminals rather than issuing fines for those overstaying 2minutes.
Ok, I found it and now need to clarify my points.
It's called the SEINS program (which is short for Self-Enforcing Infringement Notice Scheme) and its administered by the NSW Office of State Revenue.
SEINS basically allows other government agencies, authorities, councils and even private organisations to issue penalty infringement notices for certain types of offences. The legislative authority is listed within the
Fines Act NSW 1996 and per Schedule 1:-
FINES ACT 1996 - SCHEDULE 1
Under those different legislation, the respective authority can appoint an "authorised officer" to issue penalty notice. For eg. Local Government Act allows councils to appoint Council Parking Officers; in the case of Road Laws, the Minister for Roads would have authority to delegate and in this instance delegates these authority to the Sydney Airport "parking guys".
Authorised Officer undergoes training at the OSR to assist with their duties.
When they finish training, an ''authorised officer'' can issue a penalty notices. Per requirement, the original copy is forwared to the OSR, a duplicate copy is kept by the authority for future reference and auditing, and the last copy is given to the alleged offender.
OSR - can access personal information in its course of duties and as declared allowable by the Privacy Commissioner NSW - and will issue penalty reminder/warning letters, review initial appeal letters, and the collection of fines and transfer of monies.
The OSR has effectively commercialised its services and will enter into contractual agreement for its SEINS program with various organisations. And for OSR's service, they will deduct a FEE for each infringement notice it administers. So say if a parking fine is $100 and issued by Sydney Aiport, they will (say) deduct $30 for their services, and send $70 to Sydney Airport.
The SEINS scheme is continually audited by not only the OSR but the Ombudsmans Office and ICAC.
I hope this helps.
