What's wrong with speculation?  As long as it's not cybersquatting,
typo-squatting or a deliberate case of "front-running," and these are
already covered by existing policies and Code of Practice.

Not sure it's necessary... though a standard "no-transfers within
first 30 days of creation" wouldn't bother me, I think six months
is a bit excessive.

This would be a backward step... geez - we have more than
that ourselves!   Absolutely unacceptable restriction... we need
more liberalisation of the .au namespace, not less!

Don't see the benefit in that myself...

Also complicates things too much... the ability for the client to
"lock domain" is all you really need - just to protect users, etc..
and there's no reason that should cost extra.
