There's certainly going to be a lot of hurt in Australia, though some cities are turning that around. When I visited Melbourne there was some fresh looking cycling infrastructure and they're finally getting a train to their airport. Sydney's public transit was also easier to use than the last time I was there (more than 10 years ago).

Hopefully this crisis helps my aussie friends focus their efforts on funding and completing their shovel ready transit projects. :)

Any and all reliance on energy from a foreign source is a national security risk. Many nations are going to be finding that out in a very painful way soon.
