Australia is great at many things. Attracting musical talent isn’t one of them. If you go to a big Aussie music festival you can’t be too surprised or disappointed if it’s headlined by a tap dancing chook. Which is a bad example because that’d obviously be sick.
Australia is too far, has too few people, and is too expensive to tour. When the Rolling Stones hit Adelaide in 2015 I’m pretty sure I saw Mick Jagger squint and mutter ‘Prague’s changed a bit.’
