Just uploaded the ozpost module into clean install v1.5.4 and everything looks great ............. however one small problem.

We only use Australia Post and Fastway, have selected Regular Australia Post Parcels and all Fastway labels.

When checking out, if the Fastway cost is less than Australia Post and you select Fastway, when you go to payment page, it automatically changes it to the more expensive AusPost.

Have found everything works okay when Auspost is cheaper than Fastway, but problem only occurs when Fastway is cheaper than Auspost and you select Fastway.
