You can order them online from lureworld. Compleat Angler also has a city store - 3rd floor in the Dymocks Building in George St, between King and Market Sts. Ottos in Drummoyne (Victoria Rd) also has them.
Jeffo, if you have looked in wollongong at a couple places and had no joy i would say try Otto's or Austalian Bass Angler over at penrith and they should have them. I used to buy from Ottos or the bass angler as they had a good range of lures in this size. or check out campbells protackle or a couple of the online stores...but if you are likeme... you like to see it in person and then decide
