A service station attendant has been wounded with a knife during a string of violent armed robberies in Canberra.

Around 2:30am (AEST) on Thursday, a man and woman entered a Woolworths service station at Hume in Canberra’s south.

Police said the woman, armed with a knife, approached the male staff member demanding cash and struck his face, wounding him.

Both the man and woman fled with a sum of cash.

Paramedics were called and the attendant was taken to Canberra Hospital for treatment.

Just 20 minutes earlier the pair allegedly entered the BP service station in Fyshwick, threatening an attendant with a knife and demanding cash and cigarettes.

The cash was handed over and the pair fled on a motorbike with L-plates attached.

It is alleged they then attended the 7-Eleven service station on Canberra Avenue, forcing entry to the building before trying to gain access to the cash register.

They left separately, the man on the motorcycle and the woman in a grey Toyota Hilux.

CCTV footage of the incidents has not been released.

ACT police are now appealing for any witnesses to come forward, with both alleged offenders described as about 160cm tall.

The man has a solid build, and the woman has a slim build.
