If I was to guess, I think it may be an issue relating to going concern. If you look at the share purchase plan prospectus, on a pro forma basis, I think they had net cash of $2M. That was after $3M capital raise. If you compare that to qtrly reports, where they were spending $1.5M - $2M per quarter. They may not have enough money in the tin, for auditors to sign-off. I would think PWC are more strict than other auditors. Could also be that auditor in charge was away on friday and today, and that it was not signed off. It is a long weekend in sydney. Time will tell.
