Is it the chicken loop itself or the short safety line for the spinning bar system, i.e. the line going to the back of the trim strap to your safety?
Most Naish dealers should be able to help you with the chicken loop but from what I know about the trim safety line, you can't get them in Oz unless a shop has one left over from their shipment or your local shop is willing to make one up for you.
Try your local shop first sharkbait or let us know if you need further help.
