April 7 marks World Health Day, a day that gives us a chance to take action on serious health topics. This year's theme is depression, a serious but preventable and treatable disease.

Depression isn't an easy subject to cover but it's something that affects around 1 million Australians per year. It's extremely important we do talk about it because in extreme cases it can lead to suicide, which is now the second leading cause of death among 15-29 year olds according to the World Health Organization.

The good news is there are ways you can help! A career in the mental health field can ultimately be very rewarding but be ready to put in the work. If you're interested in the mental health field, TAFE NSW offers a number of courses to prepare you for a variety of positions.
