'Opposite direction' departure, CBR 28/2

[Rowan McKeever]

Hi All

Was listening to CBR ATC on the way home tonight & heard a QF B73H was awaiting departure from 17 while arrivals were inbound for 35. QF961 was slowed to 230kt on descent for sequencing with the opposite direction departure, & the last landing I heard was QF834 by which time it hadn't taken off & I lost signal. 961 was told the opposite direction was 'due a requirement'.

Wondering if anyone has info on the oddball departure, ie the flight number & perhaps the 'requirement'??

Thanks in advance. Rowan
