My daughter lives in Australia, I'm glad I don't live there. Although we were there for a few weeks without seeing any and it was only on the last day she showed me a Redback that I hadn't seen earlier, although there was a big one in her car once, made me shiver.
She now lives in the countryside and if she goes out in her garden at night with a torch the whole place lights up with spiders eyes reflecting back
An English person who's scared of spiders travels to Australia for a holiday. They're pretty wound up about the spiders. Everyone knows Australia is full of great big deadly poisonous spiders. It's all over the internet. Spiders everywhere. Probably more spiders than people!
They work themselves into a bit of a panic on the flight over and when they land they head straight to the nearest place for a drink and to get a grip. They're about to sit down when they realise they're in Australia, home of the multitude of great big deadly poisonous spiders, and should check for spiders before sitting down. Maybe there's a spider under the table. Maybe under the chair. Must remember to check!
An Australian nearby sees them, realises what they're doing and why and wanders over to reassure them. They tell the English person that aren't any dangerous spiders in this part of Australia. There are in some parts of Australia, but not around here. The English person calms down, assured that there aren't any dangerous spiders in this particular part of Australia and seeing the reasonableness of it in their head. There's a lot of sensationalising on the internet, everyone knows that. Australia's a big place. Makes sense that some wildlife would be found in some parts of it and not in other parts of it. So no dangerous spiders around here.
The Australian looks thoughtful and says "I reckon it's because the deadly poisonous snakes round here ate them all".
