Yes we have compulsory attendance. You also do not need to show any ID. Your word is good enough. The electoral roll gets cross-referenced and there are penalties for multiple votes. Apart from the joy of voting, at every place of voting (normally a local school or community hall) there will be some kind of fundraiser on election days. For example, the local school, whose hall that gets seconded as a voting booth, will run an event. This has led to the tradition of finding the best election sausage sizzle available. It's a national pastime in Australia!

Come on Down Under, where we use the high tech method of paper and pencil. We did have an issue recently where a few votes were lost somewhere in outback Western Australia. The solution? The High Court decided to run that component of the election again. Easy, effective, safe and occasionally expensive.
