Aside from membership, this is a great way to get involved.

auDA invites people with an interest in Australian (.au) domain name policy to nominate for the 2010 Names Policy Panel.
The purpose of the 2010 Names Policy Panel is to:
* review the policy framework underlying the allocation and use of
domain names in the .au domain space; and
* provide recommendations to the auDA board about what changes (if
any) should be made to the policy framework.
The Panel is expected to commence work in September 2010.
