The Nine network can be pretty slippery when it comes to describing
its shows as live and my bet is that Sunday’s two-hour special with the
miners will be another example: a delayed telecast being pumped up as
something it’s not.

Nine’s handling of the charity concert in Beaconsfield during the AFL and NRL Footy
is a case in point. Viewers were led to believe the crosses
were live, and indeed they appeared so. But there
was a giveaway: the first segment went for more than 20 minutes without an ad
break, not a normal occurrence on commercial TV.

questioned about this a Nine spokesman said this

Beaconsfield Bash – the address of thanks by
Russell and Webb – was never described/promoted anywhere
as being “live”. Due to the technicalities (and a bit like the Logies) the segment was a delayed telecast by about 40

Which is understandable, but not strictly speaking true, as you can seen from this Nine release from last week:

Footy Show
will cross live tonight to a special Nine Network goodwill event in
the Tasmanian mining town of Beaconsfield to thank locals for their support
as the incredible rescue of the brave pair unfolded.

The special
event will be hosted by Tony Jones and feature Nine Chief Executive Eddie
McGuire. From 9.30pm, The Footy Show’s Dermott Brereton and Billy Brownless will report live from the Beaconsfield Community
Hall, joined by Jason McCartney and Nathan Brown.
