What's the longest you've ever had to wait in line to vote? Where in the world?

Australia (Sydney). A few years ago I went and there was a queue going outside the door and volunteers were telling people that it would take 30-45 minutes but to please stay in line. They were also handing out Tim Tams for people in line. I decided to try another polling station instead, which was 10-15 minutes walk away. There was no queue at all there so I was out within a couple minutes. So that one took the longest even though most of it was walking to another location. Wish there was a way to tell the people in that queue that other locations were empty.
