Either spray them with a diluted chilli pepper spray, or just manually pick them all off, and take off any curled up leaves. Try and get them before they do that curly up thing, obviously otherwise you wont have any leaves yet. I would try the chilli pepper spray. Sounds like they're doing (Ironically, looking at your icon) a Hungry Caterpillar thing, and about to transfer into beautiful... moths! I think they'll turn out to be (what I'd call) cabbage moths.
Never used chilli spray. Given I've had grubs like this eating my chilli and capsicums, I'de use coffee instead (it also works wonders vs snails and slaters).
Add coffee grounds and crushed garlic to hot water. Cool and filter it into a spray bottle. Keeps most things off your plants.
