Which golf clubs should I be looking at if I want to spend between 1000 to 1500 Australian dollars?

The ones that feel best when you hit them. Look at club demo days put on by the various manufacturers and visit your local Golf shops. Find a club that is pleasing to the eye, performs well, and lends itself to a bit of custom fitting. Provided you have solid fundamentals, knowledge of the game, and good mechanics, the club that responds best when you hit it is the one to buy. Should that set cost less that 1000 Australian dollars, all the better!
