Poison Dwarf you've wasted more than just your own time contributing on these forums but here goes,
Fatal accident rates per 100,000 hrs flown GA.
.........Oz Canada US
1990 1.41 1.87 1.55
1991 1.20 2.79 1.56
1992 1.51 1.99 1.80
1993 1.29 2.01 1.75
1994 1.47 1.28 1.81
1995 1.25 2.19 1.65
1996 1.28 1.64 1.45
1997 0.92 1.55 1.38
1998 1.22 1.21 1.45
1999 1.14 1.18 1.16
2000 1.00 1.29 1.11
So you will note the U.S.A in these ten years in fact never had a lower fatal accident rate than Australia.
And then we come to the Number of fatalities in these accidents.
GA fatalities per 100,000 hours flown.

1990 3.00 3.73 2.69
1991 2.57 4.63 2.84
1992 2.97 3.15 3.46
1993 2.70 3.98 3.23

1995 2.10 4.13 2.95

1999 2.17 2.32 2.14
2000 1.81 2.15 1.92
Whether the US has a 100 trillion hours flown and Australia has 100,000 hours flown by GA, these figures are accidents per 100,000 hours flown. The only effect higher traffic density would have would be an increased number of mid air collisions between the GA traffic, and this is a miniscule proportion of the above quoted figures, or as AOPA America puts it in their report on GA accident rates for 2000,
The number of mid-air collisions increased by one to 18 in 2000, with ten accidents resulting in fatalities. "Mid-air collisions are still extraordinarily rare, less than 1% of all accidents, and the number of mid-airs remains fairly constant year to year," said Landsberg.
Removing those from the equation Australia still has a lower number of fatal accidents and a lower number of fatalities per 100,000 hrs flown than the U.S.A (and Canada)
Maybe you could visit the library dwarf and unlike Dick Smith and his cronies, actually back up what they say with figures from credible sources. I look forward to your response. And while you are at it, rather than again saying airline pilots and controllers should not design airspace, please tell us all who should. You said "Airspace Designers"???? Which university or school of further learning runs the Airspace Designers course????
