mealworm
hey there duke,
you can try personal pet services, they are located at highvale which is somewhere in or near brisbane i believe, they do them at $35 a kilo plus freight of about $10 tops.
they do all sorts of food items - woodies, crickets, silkworms, maggots etc.
i found them a lot better and friendlier than pisces who wouldn't even deal with me because i wasn't a zoo or commercial venture.
their number is 07-3289 5286
hope this helps you out,
bombie
