Expert reviews of the ACCC’s airport monitoring methodology

  03.02.2011    

Sydney Airport has released two expert reviews of the methodology used by the ACCC in its quality of service monitoring at Australia’s major airports. 
The two reviews have been independently undertaken by the University of Melbourne’s Statistical Consulting Centre and the professional research firm GA Research. 
The CEO of Sydney Airport, Russell Balding, said that the two reviews give rise to serious concerns about the ACCC’s methodological approach. 
“Sydney Airport has long been concerned about the poor methodology used by the ACCC in its monitoring reports. Last year’s ACCC report showed no sign of the methodology being improved.   
“It still did not publish basic, indeed fundamental, methodological information such as sample sizes, margins of error and response rates.   
“Without this essential methodological information, it is not possible to meaningfully interpret research,” Mr Balding said. 
“Sydney Airport therefore commissioned the University of Melbourne’s Statistical Consulting Centre and GA Research to independently review the methodology used by the ACCC and to compare it with the accepted professional standards of market and social research in Australia.  
“Both the University of Melbourne’s Statistical Consulting Centre and GA Research have considerable expertise in market research and statistical analysis and are well qualified to review the ACCC’s methodology. 
“I believe that the methodological shortcomings that have been identified and documented in the two reviews are serious.  
“The two reviews have been provided to the ACCC and will also be submitted to the current Productivity Commission inquiry into the regulation of Australia’s airports.
