Companies are the core units of Girls' Brigade. They are generally a single unit that meets together weekly. The leader of each company is the Captain who is appointed by the local church to which the Brigade is affiliated.
 
Companies are divided up by age groups into units to foster all important relationships between peers and leaders and enable age- appropriate activities and discussions.  These groups, coupled with the weekly activities, camps and outings, assist in developing social and life skills, a personal faith in God,and help the girls create long lasting friendships.

Cadets - First year of schooling to Year 2
Juniors - Year 3 to Year 6
Seniors - Year 7 to Year 8
Pioneers - Year 9 to 18 years
Young Leaders - 18+

Companies are free to organise their meetings so that they meet the needs of the girls in their company.  Whilst Girls' Brigade provides a well balanced, creative and effective program, the girls are the most important part of Girls' Brigade and why we seek to help them "become followers of the Lord Jesus Christ".

Girls have the opportunity to remain in a Company as a leader after they have reached the maximum age for the highest unit of Pioneers. Pioneers receive many opportunities to develop their leadershsip skills and we value this part of our program as we grow girls into leaders and encourage them to serve in their church and local community.
