I have not personally been involved in any. Though I am aware of the company's involvement with United Way Australia and Highschool mentoring programs that we can contribute to.
There are a lot of volunteering and charity opportunities e.g. Soccer day, walks etc
They work closely with United Way to provide resources and support to disadvantaged children. It's a really nice charity and they provide plenty of opportunities to get involved. Later this month I'll be helping run practice job interviews at a high school involved in the program.
The company provides numerous projects internally to work on.
