Just as an extra side not I belive that there is a counter terrorism unit being set up on Garden Island. I cant remember the full details, but I thought they were bringing down a couple of blackhawks to base there.
As usual though the BK is more window dressing for the gulluble NSW voters. If they buy a helicopter the government can say "look at all we are doing" reguardless of the effectiveness.
Although with the NSW gov being rabidly anti helicopter, its amazing they even know what they look like. How many other citys around the would, with a population over 5 mil, dont have a city heliport?
