In case you needed more evidence that Australia runs slightly sideways, look no further than its weirdest postcodes. Turns out 1234 isn’t a password — it's an actual place you can live (hi, Nowhere, NSW). From 4000 in Brisbane (sounds like a secret agent’s hotel room) to 0800 in Darwin (basically a hotline to crocodiles), our postcodes range from oddly satisfying to straight-up chaotic.

Some of these combinations feel like they were picked by a toddler mashing a keypad. Others, like 6999, are just begging for someone to snicker immaturely. And then there's 9999, which sounds less like a postal area and more like the emergency code you shout when you realise you’ve moved somewhere with no Uber Eats.

This oddball system isn’t just for laughs — postcodes dictate everything from insurance premiums to weird local pride rituals. Yet despite their importance, no one talks about them until you’re stuck explaining to a customer service rep that no, you’re not pranking them, you really do live in 0810.

Latest update: Australia Post has no plans to fix the chaos, because honestly, it’s kind of part of the charm. Plus, who doesn't want to feel like they’re sending mail to a glitch in the matrix? Sources: 9News, "Australia’s quirkiest postcodes revealed," 29 April 2025
