South Australia's Premier Steven Marshall has signed off on the controversial reappointment of the head of the state's remote Aboriginal lands for a further three years.

The Premier confirmed he had reappointed Richard King as Anangu Pitjantjatjara Yankunytjatjara general manager.

The move has drawn criticism from some traditional owners from the APY Lands, which encompass some 105,000 square kilometres in the north of South Australia, an area larger than Iceland, and home to around 2,500 people.

Frank Young, a traditional owner from Watarru, warned the reappointment of Mr King to the highly paid role of general manager was made despite a split between elected traditional owners over who should be in the role.
