Ran across this a few minutes ago.
From that article.....
Narrative:
Two Eurocopter EC 130B4 helicopters of Sea World Helicopters suffered a mid-air collision near Sea World Heliport (YSWD), Main Beach, Queensland.
VH-XKQ was departing Sea World Heliport when the tail section was cut off by the approaching VH-XH9 and it crashed nose down onto a sand bank and VH-XH9 made an emergency landing on the same sand bank with severe damage to the cockpit section.
Four of the seven occupants died and three received critical injuries. Five of the six occupants of the VH-XH9 received minor injuries by cockpit glass debris.
