Interesting Movements over Sydney on Mon

[Graham F]

While watching an ADSB track I noticed some odd movements of a QFA114. I then watched what happened on Webtrak. This occurred at 1:45pm on Mon 14/12 .
QFA114 from Auckland to Sydney crosses the coast north of Manly and heads WSW to line up 16R, however it goes beyond the normal line up point and gets to Ryde before making a sudden turn to the SE to try and get back to the runway path. At around Canterbury at a height of 416m it aborts the landing and turns NW and then N to Cheltenham. It has now climbed to 900m, but in attempting to rejoin the landing queue it causes Jetstar JST955 which is at a height of 1250m and already lined up to make a sudden avoidance movement to the east. JST955 eventually lines up on 16L while QF114 continues on its merry way and lands on 16R. I estimate that their separation distance was less than 5km when the avoidance manoeuvre took place.
The question was this a controller error/s or pilot fault?

5km is a huge separation at low speed in controlled airspace.

I'd hardly think there was any danger involved to either aircraft.

Glad I wasnt the only one to find that a bit weird....

To Daniel or anyone for that fact,
How does one use a adsb track in google earth??

Doesn't matter how close they get laterally if you have the required spacing vertically...

Probably 200m vertical difference at the time they were heading at each other, at a ground distance of 3.3km (white line along ground)

I put in Kropp and Cathy and some heights fore reference.

I tried attaching a KMZ file for the above but I couldnt get it to work.
