On Old Millhillians Day, OMs are kindly welcomed back to the school as guests of the Foundation. The event takes place in late June. Lunch and Tea are generously provided by the Foundation.

In addition to being able to catch up with friends, OMs can also enjoy watching – or taking part in – an afternoon of sport. An OMs cricket team plays the school 1st XI. The OMs ladies hockey team plays the school 1st XI. And energetic OMs get to play touch rugby on Memorial Field.
