Police are investigating a second aggravated robbery of a Curletts Rd dairy at around 1pm yesterday.
A man entered the store with an axe and demanded money from the shop assistant before fleeing, police say.
Police have obtained CCTV footage from the Curletts Rd robbery and would like help from the public to identify the male in the footage.
Police are working with shop staff who are understandably shaken by the events.
Police believe the two robberies could be related.
