Not sure if you can get them in Australia, but have you considered the Takahashi TOA-130NS: seems about the same price landed, and available from Claude at Astronomy and Electronics?
I have used the Tec 140, when I was in France on holidays and it was very nice- but when I got home and got my Tak TSA 102 out I felt the Tec suffered a bit by comparison.
Haven't used the Williams FLT-132, although I have used a number of other Williams refractors, but I suspect it is not in the same class...
Of course, if you want to wait forever, there is always the AP 130mm f/6.3 StarFire EDF "Gran Turismo"...

Good luck with the decision making.
