The Grey Junes are the moms of Grey Junior who volunteer to help out at the school in many different areas. The moms are organized by a committee of ladies, who work in the background to ensure the smooth running of social, sporting and fundraising events. They are responsible for the Tuckshop, serve tea at Dexter’s Den for sporting and other functions at the school. The Junes Galley prepares lunches and meals for the staff and guests as needed. Other portfolios include clothing bank, gardening, sewing, book maintenance and flowers for the school. The committee has members who run each one of these portfolios with their valued volunteers. There are also Grade representatives on the committee who are responsible for organizing their grade cake sales and assisting at bigger events.

Some of the events include the Grade 1 & 2 Father and Son campout, Fun Run, and one of the highlights on the Grey Junes calendar is the annual Fun Day. It is held at the end of the second term and is great fun for all the boys. An AGM is held at the beginning of each year where committee members are elected.
