to this country more quickly. After leaving the forces he worked full timeas a self-employed gardener and landscaper in northern Tasmania. He started radio
broadcasting in 1967 with one of the world's first gardening talkback programs from a Launceston commercial station. In 1969 he began making weekly television programs for ABC-TV called It's Growing, at Moorills Estate, Tasmania which provided practical gardening information. During this period he helped form
the Organic Gardening and Farming Society, personally forming 20 branches in
different parts of Tasmania during a two-year period. Today Peter is best known as
the presenter of the nationwide Gardening Australia program on ABC TV. After experiencing three wars he continues to be actively involved with any anti-war movements, is deeply involved with environmental campaigns and is strongly
opposed to any form of racial, religious, class, sexual or any other form of discrimination.
