There is an initial outlay, a capital cost. There's obviously going to be a maintenance cost as well and there's an operational cost, both in terms of personnel to deploy the booms. And in terms of timing, it's going to take 20-30 minutes, I suppose, at each end of the operation to deploy them, and then to stow them away and reel them back in at the end of the operation. Beyond containment booms, the Sydney oil spill has led to demands for a national reassessment of how the oil industry does business. Well, today we're calling for a Senate inquiry into the risks associated with oil spills, with exploration production and facilities like in Sydney Harbour, so we know what action can be taken to reduce oil spills around Australia.
Oil spills are a regular occurrence.
The Sydney oil spill right now and recently a major oil spill, in fact three times bigger than Sydney, adjacent to Adelaide, we've had spills on the Great Barrier Reef. So I think it's not an overreaction and particularly when you consider how sensitive either our harbours or our great marine environments are. So it's better to take action now to reduce risks, rather than wait till we have continual spills and, heaven forbid, but if we had a major disast er with a spill. The Australian Institute of Petroleum says a national inquiry is not needed. The industry, it says, learns from each accident.
