plenty on the market besty but make sure you buy from an Australian manufacturer as they need to be be big & strong to handle a cod.Brands to look for include bassman,mudguts,lurestrike,ballsnAll,auspin, sweetwater, lureproject, weavers lures, snapback....personally I like a twin colorado blade setup on a 5/8 oz jighead fished with a soft plastic & stinger hook.Best to keep a variety of different weights from 1/2 oz to 1 oz & blade configuarations (willow & colorado) in your tacklebox to suit the different conditions you may be faced with, eg depth & current.whilst you're at it try some "chatterbait " style lures as well from the manufacturers mentioned
