Tenders for the CSIRO scour closed at 5:00 pm AEST today (29 August 2008). According to the tender document late tenders will be accepted if the late receipt was caused by a mishandling error of Australia Post. I would therefore assume that reasonable time will be allowed for any late tenders to arrive before all tenders are assessed and a winner announced.
I shall post a notice on this blog, when I learn the outcome of the tender exercise.
