Peter's career has included fifteen years in fruit and nut research and extension at the Stoneville Horticultural Reseach Station, followed by ten years as senior horticultural officer at the W.A. Department of Agriculture's Garden Advisory Centre and Small Property Advisory Service. He has lectured at TAFE, Curtin University and other tertiary instiutions, run short courses and seminars for the public, and managed his family orchard and nursery in the Hills. He is also a regular speaker at field days, Garden Week, Curtin and ABC radio. In addition, Peter is a member of the Great Gardens team, presenting free workshops all over the state explaining and promoting sustainable gardening and property management.

Training and education are a passion and he actively supports the planting of trees for fruit, nut or timber production, not just as ornamentals. As a footnote his passion for tree crops, especially macadamia nuts, has led to a fascination for Australian native culinary and medicinal plant species, and he donates considerable time to promoting them.
