"The ATSB final report notes that, in the last decade in Australia,
there have been eight loss of separation occurrences involving aircraft
cleared on a SID, where a following aircraft has climbed faster than the
preceding aircraft.

Of these, six were at Sydney, and five involved the DEENA 7 SID."

Seems like the issue should have been addressed before now.

What matters is how bad the loss of separation actually was.

Regardless of how close things got on previous occasions, the risk
presented by a faster climbing aircraft turning inside a slower climbing
aircraft should have been recognised.

Especially since its happened on 6 previous occasions.
2.4 kms is hardly a near miss but well short if the recommended 4km.
