During World War II the Japanese started an advance down the Kokoda Track through what is now Papua New Guinea, looking to annex the place to isolate Australia. The Australians were having none of that and so there was a series of battles along the length of the track. Those battles have left behind an awful lot of war debris; when you're firing on an enemy you're not really going to pick up the shell casings your gun is spitting out. Then, when you win, you just pack up, head off and leave all sorts of crap behind. The local population has become quite good at re-purposing some of that stuff to build homes. But obviously not with the hand grenades and other explosive items that were left behind. This documentary looks at the efforts of some battlefield archaeologists to uncover some of this debris, and also any human remains they can find. The most impressive thing about that is how they manage to figure out where to dig in the middle of a jungle that's had more than 70 years of growth since the war. You know that "democracy manifest" guy who turned into a meme? He was the guy who, while being arrested by police outside a restaurant, wondered if the charge was "eating a succulent Chinese meal". Well, he actually makes an appearance in this episode of Armed and Dangerous, which deals with some of the more audacious prison breakouts in Australia. While he has gone by various names over the years, here he is called Jack Karlson. He managed to escape from the holding cells beneath the courts in 1968. He noticed there were detectives in the cells interviewing other prisoners. So he has the idea to pretend he's a police detective himself - largely by wearing a hat like other coppers - and drag a fellow crim out of the cells as though he was being taken to court. And it actually worked. It's one of several fascinating escape stories - the others include the Boggo Road fun run where a bunch of prisoners raced out an open gate of the notorious Queensland prison, and an effort of some crims to tunnel their way out of Parramatta jail. They would have gotten away with it too, had one of the diggers not slipped up. I recall a few episodes of this series airing earlier this year and then the network must have gone off it, because this is episode three. Not sure why they would have done that; as far as commercial TV crime doco series, this is one of the better ones. Just try and overlook the intensely blokey voiceovers. This final episode of the series shows the conclusion of the massive redesign of the opera house to improve its oft-criticised acoustic issues. There's a bit of a rush because it needs to be sorted in time for opening night. It should make for an episode full of tension, but it didn't end up that way. Instead, it all feels rather dull.
