United care is a community service agency of the Uniting Church in Australia and forms part of the national Uniting Care Network.
They provide a wide range of services including shelter for the homeless, financial support, counseling, training and a range of other programs for bringing families together.
Gillian volunteers for this charity because she wants to encourage young people to do the same.
She feels that it helps to build their confidence, interpersonal, customer service and communication skills.
(Plus it looks good on your resume.)
Not only that volunteering is also a great way to get character references which are useful for those who have just finished school, and are entering into the job market.
