Volunteering in the environmental sector
Many people have noticed the catch-22 situation in which it's hard to get a job without experience and hard to get experience without a job. This is where volunteer work comes in. Volunteering for an environmental organisation can give you the experience you need, the opportunity to learn about the organisation and industry, as well as "a foot in the door" so you're in the right place if a paid job opportunity does arise. Volunteering is a great way to meet like-minded people and share experiences of the job market, pass on hints, and find out about jobs that you may not have heard of otherwise.
Volunteering is also a great way to simply help out with a cause you believe in. Many environmental organisations would not be able to operate without volunteers, illustrated by a great quote from an American movie: "There is nothing stronger than the heart of the volunteer".
If you want to do volunteer work, a starting point would be to check with your local council to find out about things occurring in your area. It is especially good to find out about local ‘friends’ groups who may be involved in environmental activities in your area, for example Friends Of The Earth or Friends of Merri Creek
