Here are a few images of BK117 LIFE21 operating at 200ft over Kurnell. The overflying aircraft on approach are directly above at 1000ft, so ATC were
understandably cautious. Range to the BK117 is 7km.
Channel 7 AS.355F1 chopper VH-SEV is now operating in the same area, and ATC are asking them to move east with each approaching arrival.
This is a Jetstar A320 overhead the same point where LIFE21 was operating
