Wollongong City Council has received a development application to build the restaurant and a service station on King Street between Turpin Avenue and Montgomery Avenue.

The site formerly held a Nissan and Suzuki car dealership, the buildings of which would be demolished under the proposal.

Carl's Jr is a burger restaurant with a presence in 42 countries, but it is relatively new in Australia and if the Warrawong proposal is successful, it will become only its fourth restaurant in NSW and the first in the Illawarra.

The proposed restaurant would include 20 seats for dine-in patrons and a drive-through for takeaway.

The developers anticipate takeaway would form the bulk of trade.

The application documents state that the restaurant would employ about 40 people in full-time and part-time positions.

Australian-owned Jasbe Petroleum would operate the service station, which would employ seven to 10 people.

It is proposed that both the service station and Carl's Jr would operate from 6am to midnight, seven days a week.

There are existing driveways into the site on King and Mowbray streets; it is proposed the King Street driveway would only permit cars to turn left to enter and exit, while motorists could turn in and out either direction.

"The proposed construction and use of a service station and takeaway food and drink premises with drive thru will allow for an aesthetically pleasing and functional development on what is currently underdeveloped and unutilised land," an application document said.

The application is on public exhibition on the council's website until June 24.
