That isn't true. Here in Australia the typical notice period is two weeks. That means if you want to leave, you write a resignation letter and you have time to hand over like you said. However the employer might also walk you out of the building and continue to pay you for two weeks. I've seen this happen here. In some companies it depends on the job you're resigning from. I happen to know my position at my company has the former sort of relaxed notice period, but other positions have the latter sort of strict notice period. It's very strange.
