Swimming Australia will install an interim head coach ahead of next month's national championships following the resignation of Leigh Nugent.
Swimming Australia president Barclay Nettlefold was keen to stress Nugent, who took up the role in 2009, had vacated his position on his own volition rather than been sacked.
"Leigh actually approached us to discuss his future and where he would best fit into the new structure of the high performance unit," Nettlefold said.
"In those discussions it soon became very clear that while he still wanted to remain involved in the sport, he didn't want to continue in the position of head coach."
Nettlefold also confirmed that Swimming Australia would announce their new chief executive and high performance director in time for the Australian championships, which run from April 26 to May 3 at Adelaide's SA Aquatic & Leisure Centre.
"There will be a new leadership structure for the organisation for the Australian championships and the aim of that structure is to provide our elite and up-and-coming athletes and coaches with the best environment to succeed," Nettlefold said.
"We have a preferred candidate for the CEO position in Mark Anderson from Hockey Australia, and will look to finalise his appointment next week.
"Similarly we have narrowed the director of high performance down to a preference of two candidates and will consult with the new CEO and high performance committee before finalising that appointment."
Nugent's position was under threat ever since Australia's swimmers left the 2012 Olympics with just one gold medal, obtained in the women's 4x100m freestyle relay.
After winning five golds in the pool at Sydney 2000, the Australians netted seven in Athens in 2004 before claiming six in Beijing four years later.
