Those tugs are not necessarily available to us on demand for a spill. That's the problem with relying on the private sector assets. Those two tugs just happened to be in Victoria at the right time. We need reliable capacity for responding to spills that we can call on when we need it.
So yes, I'm suggesting that the federal government should invest in it and that it should be paid for, at least in part, by a levy on the shippers.
