Emilio, population size has a fair bit to do with this, I think. You have to remember two things:
1) The majority of any given population will listen to crappy mainstream music;
2) Australia has a relatively small population (20 million people).
Take those two things together and you realise that the "indie" community in Australia is much smaller than in somewhere such as the U.S. or the U.K. And while Triple-J markets itself as an "alternative" radio station, and while it certainly plays a hell of a lot more new music than the other major pop stations in Australia, it's still very much a mainstream station in a lot of ways: by and large it's no longer interested in playing stuff that might weird people out, or which listeners might have difficulty fitting into preconceived notions of music, or which in general will be outside their realm of musical experience. Which is why on a list such as this you get a preponderance of crappy music: because (A) most of the music that Triple-J plays is crappy anyway, and (B) even when Triple-J plays non-crappy music, the fairly mainstream tastes of the audience will dictate that it's the crappy that wins out. Were an independent (and much smaller) radio station such as Triple-R in Melbourne to do a similar end-of-year list, the result would be quite different.
