The surviving son of a former Australian family who were axed to death in South Africa has handed himself into police in South Africa.
South Africa media is reporting Henri van Breda, 21, arrived at the Stellenbosch Police station with his attorney on Monday in connection with the attack on his family. 
Martin van Breda ??? 54??? his wife Teresa??? 55??? and their elder son??? Rudi??? 22??? were found axed to death in their home on the De Zalze Golf Estate on 27   January 2015.
No arrests have been made over the killings.
At the time, Henri told police told he was attacked last and was knocked unconscious, next to his mother and sister Marli, 17, who also survived the attack.
At the time of the attack, doctors said Henri's wounds - a bruise to the head and scratches - were self-inflicted and he waited up to four hours before calling emergency services after his family was slain.
He had enlisted high-profile South African defence lawyer Pieter Botha, who famously defended British millionaire Shrien Dewani - who was accused of killing his wife Anne during their honeymoon in South Africa in 2010. The charges were dismissed in 2014.
A triple-0 call Henri made after the attack appears to have him snigger when telling the operator members of his family were "bleeding from the head".
The van Breda family, originally from South Africa, settled in Perth about eight years ago, before moving to Buderim on the Sunshine Coast between 2012 and 2014.
Mr van Breda was managing director of the Australian franchise of Engel & V&ouml;lkers, an international company that sells and rents "premium residential property, commercial real estate and yachts", according to its website.
The family had moved from Perth in 2010 so that Mr van Breda could establish the first Australian branch of luxury German real estate brand in Mooloolaba.
Sunshine Coast real estate agent Paul Freney Mr van Breda returned to his South African homeland with his family to establish a private school, his area of expertise.
Karen Sadler, whose daughter went to Presbyterian Ladies College in Perth with Marli for about seven years, described the van Breda family as "a beautiful, gorgeous family and very close."
