Petra: actual standalone, part of a series or just a single episode being shown

[prl]

IceTV lists Petra: Lost City of Stone (SBS 19:35, Sun, 1 May) as a single show, not a series.

Is it the episode of that name of History's Mysteries from 2001, the episode of that name from Nova from 2015, or something else entirely? There's something completely different in that timeslot on 8 May, so is SBS just grabbing a random episode as a filler?

Hi PRL,
I am sorry I can't tell you for sure, as SBS has not given out that information. This episode aired previously on 16/8/15 if that helps you at all.

Thanks, Alison. I'd guess it's probably from the Nova series and that we saw it first time round.
