On Guard...got to agree with you on BNE being the worst,I go through that transit screening point twice a month either on route to PNG or back home to Auckland,about 18months ago while heading to PNG my "Computer bag" tested positive for explosives,I could not believe what occured for the next 45mins....surrounded by 4 armed policeman,ask some very stupid questions,then was told it was up to the Airline if they wished to carry me (it was PX they carry anybody so not a problem) I have never had any contact with explosives,maybe except on "Guy Falks night,and it was the wrong time of the year....had to be equipment failure,my computer bag is the same one I have always used and still do....
