AS55 Around Sydney

[Garry Emanuel]

Anyone know what the purpose of the flight this morning of an AS55 chopper from Bankstown that did a range of loops around the Shire, inner and southern suburbs before returning to Bankstown ?

When they passed over Barden Ridge, height seemed low and the speed was slow too - couldn't see if there was a film crew or some form of surveillance equipment and not able to ascertain an operator name.

Thanks in advance.
