A Bishop’s mitre above the shield was chosen to denote Peninsula Grammar's commitment to the Christian faith.

The incorporation of the Southern Cross and a torch together on a shield below the mitre symbolise our unique location in the southern hemisphere. 

The ribbons under the mitre are the traditional ribbons attached to a Bishop’s mitre.

The torch symbolises the light of learning, but is also a reference to the torch that appears on the family crest of Matthew Flinders, whom is associated with exploration of the Mornington Peninsula.
