G'day Jaba, not denying they got close and if the ATSB says 1.9 then I am not going to disagree.
Since finding these WebTrack thingies I have seen some fairly close calls but not between RPT. I recall seeing two light aircraft come within 100 metres while their images were superimposed.
Interesting that the 767 was moving so much more quickly than the 737 and climbing faster as well. I would have thought that in the terminal area they both would have been 240 - 250 knots.
