PB trained and qualified in Horticulture at Adelaide Botanic Gardens in 1977 and has been actively involved with horticulture ever since. He has owned and run several businesses including landscaping and garden maintenance, commercial pruning and chipping, and he set up a permaculture nursery and consultation service.

He has always enthusiastically worked using organic methods of horticulture and embraced Permaculture in 1988 when he undertook a consultant design course. For the next 10 years, he ran many Permaculture Design Courses in and around the Fremantle area including Murdoch Uni, Bentley TAFE, Apace and North Fremantle Permaculture Centre. Since moving to Margaret River in 1997 he has extended his interests widely to include Biodynamic agriculture and practises.

For 16 years, he worked at Cape Mentelle Vineyard taking care of the grounds and biological waste water treatment, which he instigated and set up. In 2015, he and his partner Swabodhi designed and completed their owner builder straw bale home, which gained an 8.5 NATHERS energy rating. They are now well on the way to food self-sufficiency. In late 2015, he joined the team at Witchcliffe Ecovillage as a Permaculture Design Adviser.

In 2018, PB was made a Permaculture Elder in recognition of his years of dedication and passion of permaculture.
