Sure, if you don't want to see those local networks. But since the cost
of getting from "Perth" to "! Perth" is (was?) a lot higher than what
you guys even pay for international transit at non-Cogent rates, we have
some sort of desire to keep as much traffic local as possible.

Hence "Local only" announcements.

.. and what about their customers with portable address space?
What if every single customer decides they now want to multihome, dynamic
endpoint resolution stuff (LISA?) isn't ready, and companies simply join
the RIR and buy their own IP space? :)
