For me, Ipswich, Queensland, Australia is the world's most livable city.... and it would take an almighty convincing argument to make me feel otherwise.
For one; it's because I live here and I haven't the inclination at my age to move anywhere else ever again; two, it has everything I need and more; and three, cos it's a smallish country town and is so much better than living in a sprawling metropolis with impersonal hustle-bustle everywhere and skyscrapers that block out the sun.
Nope, I never liked big cities that much, so living out here in the boondocks of Ipswich suits me perfectly. Okay, so our Bremer River isn't as impressive as the Yarra, and it's an upside down river - water on the bottom, mud on the top - but there are some nice family oriented parks and walkways beside it these days that help give Ipswich a greater feeling of community
Oh, and we don't have a congested harbour that's full of sharks, shady business ventures and likely a few underbelly figures from yesteryear, so I'm not gonna see large and impressive ocean liners, either. Bit hard 90+ klms inland, but I occasionally see a speedboat on the Bremer... and that'll do me nicely, thank you.
Yup, Ipswich, Queensland, Australia is bloody great place to be.
