The competition is open to any student in any high school or primary school in Australia.
Only one entry per student is allowed. Duplicates will be disqualified. The competition closes on August 18th.
The winner will be the earliest entry received that is closest to the estimated right answer, as judged by the "wisdom of the crowd" from all valid entries received. This answer will be posted on the MPAS website once determined. The winner will be contacted by email, and a teacher at their school will be required to reply and provide an address to which the prize can be shipped.
