Yep - they've gone to Seek after it was on the Biota site for about 3 weeks.
If I was Biota, I'd be looking to recruit in the US - the Australian market is far too small to find a selection of suitable candidates for this type of role and it might be smarter to have the person based in the US on the doorstep of BARDA and the FDA, and also if there looks like being a move there at some point...
