FJ, even in NSW year 7 isn't really classed as high school anymore apparently, but 'middle school' which is years 5-7, but mostly years 6 and 7. This is because in year 7 they still run a set curriculum with no elective subjects chosen till year 8, so even though in QLD year 7 is still primary school the level of education is still the same. I would say that he would still follow his current school year when you move.
