Third hand knowledge but, a mate of a mate who works for Fisheries in Gero did the autopsy and there was a seals top half stuck down in its throat. No reason for him to lie to us so I think that just about clears it up. Sorry if this upsets conspiracy theorists.
That is interesting. No conspiracy theory from my behalf. I said from the start the only crime was that Fisheries didn't let the sharks body be handed over to UWA Scientists or anyone who would be able to study, learn and maybe give a true understanding as to what may have killed the shark. As for your mate of a mate Grevas id be really keen to know what they did, as Rory McAulay of fisheries said they only took skin and blood samples, thats not a autopsy

So one of them is lying

Either way it would be interesting, ask him if they did actually cut up the shark or just dump the body

Oh and for having no reason to lie, well so far not a lot of truth has come from fisheries sadly..
