Yarralin Outback Airshow & Concert
The date for the Yarralin Outback Airshow has been confirmed. This stunning event will be held at the Yarralin Airstrip on Saturday August 12th 2006 from 10.00am.
The event will feature fly pasts of aircraft, parachuting display, model aircraft, aerobatic displays and more.
...and found this in the minutes:
CEO showed a video of an air-show and council discussed whether to hold an Airshow at Yarralin on Saturday August 12th 2006 – the week before the Wave Hill walk-off celebrations. Council suggested also having a bush BBQ for visitors where we cook Goanna, Bush Turkey and other meats from the area. Council asked Nick to progress the event.

All in favour
...an entirely rational process, see one on the telly and somebody says "Ah want THAT one!"
