In a welcome change, nobody has blamed RA-Aus yet

It is a collective group problem.
I could tell the story of how a good mate was almost killed 3 miles from touchdown in IMC conditions (BKN 0100) on the ILS to Willy town, to be confunted by a drifter(or similar) surfing around in the gaps between the CU and such, and not listening to the CTAF obviously.
The fact that his F/O saw it, and the 170 punters in the back had no idea how close they came, nor the folk on the ground who could have had a 737 drop in .....
Had this idiot not been about 3 seconds later, he would have caused a tragic mess.
Ballina is a classic case. The operators of B737 and most likely A320's into there love it when the weather is down to the minima......less likely to hit a big bug.
Creamie, sadly there are vastly varying standards around the country. One airfield that you know, and sounds similar to your description has few problems, because the air prox definition is life in the CTAF area. They are mostly well behaved and courteous. Other places are not so good.
