Not at the present moment but our next orders will be with them.
A transition takes some time.
For example, we are currently using an equal quality of WPI from Mullins in the U.S and although we announced about 2 months ago now that we would be switching to Fonterra NZ (due to high requests from our customers only, not that it is any different in nutritional value), a change just doesn't happen at a snap of a finger.
Consider first of all that shipping to Australia can be up to 8 weeks and then consider current stock still needing to be used.
From announcement to actual change over is quite some time. For example, an overseas supply of Whey just doesn't show up on your doorstep the next week.
In short: currently, Mullins of U.S
Transitioning back over to (we are previous customers of theirs): Fonterra NZ
As a side note, our WPC is Fonterra.
