Australia's chairman of selectors, Rod Marsh, will end his tenure in 2017 after telling Cricket Australia he will not continue beyond his current contract.
"We can confirm that Rod Marsh has decided not to continue on in his role as national selector once his contract expires in June 2017," a Cricket Australia spokesperson said. "At this stage no decision has been made on a replacement."
The 2016-17 summer will therefore be the last under the current selection panel of Marsh, Trevor Hohns, Mark Waugh and coach Darren Lehmann.
Marsh's panel oversaw a period during which Australia briefly regained the No.1 Test ranking earlier this year in New Zealand, but there have also been ongoing struggles, especially on tours away from home.
The Australians were beaten 2-0 by Pakistan in the UAE in 2014, lost the Ashes in England last year, and were humiliated 3-0 by Sri Lanka this year.
In the shorter formats, the 2015 World Cup triumph was the highlight of Marsh's time at the helm, and Australia continue to be ranked No.1 in the world in ODI cricket despite their 5-0 loss in South Africa this month.
