A security guard has been threatened with a baseball bat while being robbed at a Coffs Harbour fast food restaurant.

Police say just before 10:00am (AEDT) two men wearing hoodies and balaclavas robbed a guard outside the Park Beach McDonalds.

Detective Inspector Chris Clarke says the guard was carrying a bag with the weekend's takings to his car, when he was threatened with a wooden bat.

Inspector Clarke says the men took the cash and fled in a white car.

"The witnesses that we've interviewed so far have been able to provide us with some information concerning the motor vehicle and the description of the parties involved," he said.

"The response that we've had to calls for assistance have been very limited at this time.

"But what we're hoping for is some person may have seen these two fellas scoping out that car park sometime prior to 10:00am."

Inspector Clarke says the security guard was unhurt, but shaken.

"Any crime of this nature has its own frustrations attached to it," he said.

"This one is a lot more prevalent because these two offenders were obviously in the car park for a period of time before this incident took place."

Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
