As the map on the web page below shows, the vast majority of jet traffic
to/from Canberra Airport use the N-S runway. (The few shown doing circuit
training close to the airport and occasionally using the NW-SE runway are
almost certainly the RAAF VIP jet fleet.)
http://www.canberraairport.com.au/an_man.htm
The NW-SE runway is largely restricted to general aviation (i.e. light
aircraft), and some commercial turbo-prop aircraft (e.g. Dash-8 services
to Sydney); visitors to the Newline Quarry site may have observed the
latter, depending on the prevailing weather conditions.
Ironically, it is Jerrabomberra Wetlands proximity to the airport that
largely prevents direct overflight by jet aircraft at least. (One
unusually tight loop using the NW-SE runway is an exception.) The
noise restrictions over the Canberra suburbs also deter overflights
of the area.
Less clear is whether birds would fly through the air corridor south of
the airport - where the risk of bird strike is greatest - en route to
the Wetlands. My gut feeling from general observations around the area
is that the main thoroughfare is between Lake Burley-Griffin and the
Wetlands. Exceptions are ibis attracted to the turf farm, honeyeaters
etc. on migration (generally at low altitude), and pelicans utilising thermals.
I don't see that any changes at Jerrabomberra Wetlands would
significantly increase the chance of bird strike over the risks that
already exist, though deeper water at the Wetlands would probably
attract more pelicans to the area. An aircraft bumping into a bittern
or Painted Snipe would have to be a lot luckier - or unluckier - than
most Canberra birdos.
