I don't think Perth made the list of 72 Dangerous Places to Live (a Netflix series that Tash's mum was watching last night) due to lack of rainfall. They were scraping the barrel near the bottom of the list with Derby (the WA one) somewhere in the low 60s due to its high daily tidal changes that could catch out tourists and Wellington further down in the 60s because of... wind.

For reference many of the other places were in the list because of proximity to erupting volcanoes (this was actually quite common), regular flooding, earthquakes, extreme cold (as in -30C to -50C), radiation (Fukushima) and major pollution (pretty much any major city in India).

Would have thought that with Wellington the major potential issue would be earthquakes - there was a very big one in the 1850s which would be very destructive if repeated.

In terms of vulnerability to really serious disasters, the most susceptible Australian city is probably Cairns, because the built-up area is so low-lying - the scale of the evacuations for even a category 2 cyclone in December is an indicator of how seriously the risk is taken. Worst-case scenario is a category 5 landfall on high tide just to the north.

there were two magnitude 8.5ish on the point opposite wellington in the 1850s. lifted the seabed around 5m i think. Lucky wellington itself was still mostly a tent and wooden place then, with the far north still the center of the economy/governence.

seismic models have something like a 50:50 chance of a decent (~8+) rupture of the alpine fault in the next 50 years

Perth is windier than Wellington for sure, and now almost as dry as the Atacama desert.

Did anywhere renowned for a serial killer (eg Snowtown, Boston, Yorkshire, etc.) feature in the program? Or Midsomer for that matter? How about Esperance, Streaky Bay or Cape Province South Africa for shark attacks?

Wellington Airport's mean wind speed (25.8 km/h) is substantially higher than most of metro Perth (16.7 km/h at Perth Airport, around 21 at Swanbourne), although slightly lower than Rottnest Island. It also has higher gusts than have ever been observed in Perth (the record at the airport is 187 km/h).

Perth Airport is well inland, while Wellington’s is right on the coast in Cook Strait and facing the Southern Ocean, so Rotto is a better comparison. Wellington city is fairly well protected by higher land.

Simmo I wouldn't know, it was a six part series and as with every single program that Tash's mum watches (a viewing span that typically lasts from around 12:30pm-9:30pm), I only watched a bit of it while I was eating dinner - her viewing choices are typically not in my range of interests. Most of the places seemed to do with natural or man made disasters or weather conditions rather than the odd murderer.

Right now I think Grindavik on Iceland would be high on the list.
