Agree with most of what Lovey80 says.
I don't care if it's whales or toadfish. If Australia has a claim on this area of water, we should be defending it.
We dont have to send warships (Hell, we probably dont have any) but we should have a Navy presence there, peacefully but firmly applying pressure to the Japanese whalers (or anyone else) to depart our declared waters.
Continue the pressure on the international court & lets stop being a plaything/non entity for the self proclaimed global giants.
Whether you agree with the policy or not, at least NZ has the guts to put their money where their mouth is internationally.
