There are several things wrong actually: the missing J clue, and the omission of letter counts from both the S and the T clues. The S is perhaps understandable, given that the last part of the clue is "number of Australian states," but the absence of the T word-count had me looking for something out of the box.
It may be nitpicking, but there must be some people new to this kind of puzzle who would appreciate being told that the clue letters were also the first letters of the answers.
All of which said, it is really a very clever grid, which just clicked into place (except for that pesky T and J) once I had the double lights at K and V and three of the four ten-letter answers. I really love this kind of puzzle!
