A former Sunshine Coast man killed with his wife and one of his three children in a brutal triple axe murder in South Africa had planned to return to Australia to live, a former colleague said. Martin van Breda, 54, his wife Teresa, 55, and son Rudi, 22, were killed in the violent attack on Wednesday at De Zalze Winelands Golf Estate, an exclusive golf resort in Stellenbosch, about 50 kilometres east of Cape Town.
