Any current Suzuki mouthpiece will fit, Joanna. The best place to look is probably on eBay. Selection and prices vary from week to week, and when you find the one you want compare prices: the same mouthpiece may from one vendor cost half what it costs from another. Delivery to Australia could complicate matters. I think there are at least two different Suzuki/Hammond trumpet style mouthpieces.
