The Minister does understand that the US has a lower collision rate than Australia,a lower ATC error rate, and TIBA is unknown in US, and therefore the US must be doing something right, that we are not. All this before the arrival of Mr. McCormick and the new CASA Chairman, Dr. Hawke.
Care to state the source of your collision statistics ?, because I read in "Review of Midair Collisions Involving General Aviation Aircraft in Australia between 1961 and 2003"
http://www.atsb.gov.au/media/36828/R...midair_col.pdf that
Australia and the US had a similar rate of midair collisions involving general aviation aircraft during the period 1981-2003. The US had a higher rate of general aviation aircraft involved in collisions per flight hour away from the circuit area, which is consistent with the US having more general aviation flying activity and a higher traffic density
TIBA is a problem caused by short-sighted and bonus-driven ASA management who haven't provided enough actual working ATCOs.
