A Service NSW bus will visit Helensburgh on Thursday, May 16.
All the major transactions that are carried out at Service NSW offices will be available from the mobile centre.
The bus, which will be at Charles Harper Park from 9am to 3.30pm, is one of four launched during the state election campaign to extend services to country and regional centres.
Heathcote MP Lee Evans said the buses saved time and money for service users.
"They perform every major Service NSW transaction including driver knowledge tests as well as cost of living appointments," he said.
"Since 2013, Service NSW has been a 'one stop shop' for vital services such as getting a birth certificate, a Seniors Card, driver licence and vehicle registration.
"It is also a gateway to household savings and can help people access important cost of living programs, such as Energy Switch, $100 Active Kids and Creative vouchers and cheaper Green Slips.
"The mobile service centre will be cashless, with payment options including cheque, eftpos and credit card."
