Michael Cooney writes in The Melbourne Age that Queen's Birthday in Australia should be replaced with "Kids' Day":

THIS year should be the last Queen's Birthday long weekend. It's time to replace a holiday based on the past with a holiday based on the future. So next year, the first Monday in June should be a new public holiday: Kids' Day.

It's an interesting idea, although the author puts focus on why there should be a Kids Day, rather than why replacing the Queen's Birthday holiday is an important step forward for Australia.
