Tate, Monash and Sewell were members of the Beef Steak Club, a dining club that met monthly. Osborne and Monash belonged to the Wallaby Club, a walking club of professors, journalists, naturalists, and Scouters.

It was not a service organisation and its members were reticent about the nature of the organisation, keeping this private to their own members.
