Looks like an homalictus possibly punctuated. It was repairing its collection of mud nests which were disturbed in outside furniture. I left the photos un cropped to show the nest.
Very few Australian bees construct free-standing nests and those that do use resin and plant material. The legs and shape of the abdomen are more wasp-like than bee-like and there is no evidence of hair for transporting pollen.
Eumeninae fold their wings longitudinally when not flying, so I don’t think this is a potter wasp. I can’t tell what type of wasp it is without a closer photo
