Robin Beddings of CSIRO has provided the following reply
they are probably 'moth larvae possibly of the common cutworm. In these kind of numbers they will do considerable damage to veggie crops. Most insecticide sprays will kill them but near veggies I would recommend biological control using entomopathogenic nematodes. These are obtainable from Ecogrow in Queanbeyan and although a little expensive will kill many of your grubs within a few days when the dead grubs will each produce thousands more nematodes that should kill the rest. They come in a cellulose matrix which should be mixed with water, sprayed on the surface in the evening and then thoroughly watered in.
hanks Robin, and thanks for other respondents.
