moreover, experience hints at quality, because poor teachers will obviously be replaced by better ones in a competitive industry of education, and will endure and/or progress to higher salary tiers. surely this is "fairer" and a better indicator of quality than a multitude of hit-and-miss policies?
First of all Victoria only fired 3 of its 39,434 government school teachers in 2006:

http://econrsss.anu.edu.au/%7Ealeigh/pdf/TQPanel.pdf"The results from this paper also shed light on the extent to which uniform pay schedules, which reward teachers based solely upon qualifications and experience, capture productivity differences between teachers. It is certainly true that some of the variation between teachers can be explained by demographic factors. In both literacy and numeracy, more experienced teachers have higher test score gains. The experience effect is large in the early years of a teacher’s career, and thereafter appears to be larger for numeracy than literacy (though it is possible that this also reflects a decline in the aptitude of new teachers over time). I find suggestive evidence that students with female teachers do better in literacy, but no evidence that students do better if their teachers have higher formal qualifications. And the DETA rating does seem to capture some differences between teachers, even holding constant other characteristics.
Yet while there are some systematic patterns,
99 percent of the variation in teacher performance remains unexplained by differences in teacher demographics. This suggests that uniform pay schedules are indeed only picking up a small portion of the differences in test score gains across teachers. Assuming test score gains are an important measure of educational output, these results suggest that it may be worth considering alternative salary structures, as a means of attracting and retaining the best teachers."
Bottom line is that variation in experience only accounts for
1% of the variation in teacher performance.
But in any case, individual government schools ought to be free to choose that the compensation arrangement. Such decisions ought to be at the school level (like at every other private school) not by some bureaucrat in a distant office.
