I've got a wild theory about how the suitcase could of ended up in wynarka - sorry it's off topic compared to the current conversations but i thought i would just add my 2 cents in. And apologies in advance if someone has already said the same...
I've driven a fair bit on Australian country roads at night time, and it's not uncommon to go through a Police random booze bus and its also not uncommon to go through night time road works, these two could easily look like each other when driving at night, especially if there was a bend in the road and all you could see was bright lights up ahead. Police have stated there was road works in Wynarka before the case was found. Even if the road works were done during daytime hours flood lights ect around vehicles do get left on sometimes.
If the person who had the suitcase in there vehicle was driving through that area at night, they could of easily got spooked by the lights up ahead. They would have been on edge anyway you would think because of the contents of the suitcase. If you also add that person could of been on some type of substance that would make it even worse with paranoia. As i stated in a previous post, the police do have a right to search your vehicle.
So what im getting at is... the person could of seen these lights ahead thought it was a booze bus, dumped the suitcase in the bushes with intention to come back for it and drove through because they had to get to where they were going.
Why didn't they come back for it? The road works crew in the location might have made it too risky to return straight away without being spotted and when they did return someone could have gone through the suitcase already and moved it.
Wynarka is such a random location to dump the suitcase and this is all i could come up with. If you look at the pics i have attached you can see on the karoonda hwy photo its a bit steep and there is a bend in the road so you wouldn't have the best visibility to see for miles ahead of you at night time on that stretch of road.
