If TSX polar alignment is not working then that points to something else wrong, which may be causing this rotation.
If your location is correct and time is correct and mount is homing properly for Southern Hemisphere then TSX should work. 10 plate solves and it has all it needs to tell you how far things are off. The adjustment it then tells you to do shoudl put things within a couple of arc mins.
Solve that first and I think you will solve your current issue. There is a whole thread in PMX forum about getting polar alignment to work

Are you using latest Sky X and CCD Soft ?
I see you posted on MX forum. so you should get some answers that way.
Let us know if/when you solve it.
