On May 16 there was a public rally in Sydney as a pre-election event in support of the ABC.  A recording of this event is provided if you click on the following - https://www.facebook.com/watch/?v=515679110054706  (if no sound, click off the mute button in bottom right of the video window).

Kerry O'Brien starts with a particularly passionate and informative 15 minute talk as the first speaker of this rally.  He is then followed by Labor, Green and Independent speakers; all are worth listening to.  The Coalition was invited (Communications Minister, Paul Fletcher), but it appears there was no response.
