Queensland only has a population of about 3 million people, so the market for senior maths texts is not large. There are only a few texts available, so by default there are common texts.
Having said I like the new courses, I don't really like the new texts. In trying to have the first text on the market, the authors have produced books with some rather shocking errors. I think most teachers use the texts merely to get homework exercises.

Well, no, but I would hope that in five years time I will have found ways of teaching mathematics better, and that a visitor to my classroom would be able to notice the difference.
