Hey mate if you have Auto One down there go in there and have a look. They are pretty good normally, and the best thing is, if you get something that doesn't fit you can return it (which is what happened with my first clutch kit).
For my 2.0L, a heavy duty kit with a clamp load of 650kg (i think, it was a 40% increase regardless) was $260. Not sure if this is indicative of prices for the 1.6L.
Good luck
