As an Al language model, I do not have real-time information or access to the current events. Therefore, I cannot answer the question about the time U2 concert starts in Melbourne.

In order to get the most up-to-date and accurate information about the concert in Melbourne, I suggest you check the official website of the concert venue. You may also want to follow the social media accounts of U2 or the concert promoter for any announcements or updates regarding the concert schedule.
