I have been greatly helped in my Christian walk by the ministry of John Piper and am excited about the rich resources at Desiring God. There are thousands of articles, links to books, full copies of books to download [but you'll be better off with the hard copy, except for some of the smaller ones, I think] and the new Desiring God radio has hundreds of excellent recordings of John Piper's sermons, nicely packaged into half hour segments with short interviews with Pastor Piper, etc.
Travelling 50 kilometres to Orange to teach piano three times a week is a great experience, while I listen to the talks.
Have you read any of Piper's books? I wonder what it would take to bring him to Australia? Interested KCC?
