Elite swimming coach Peter Bishop has been stood down from his position with the South Australian Sports Institute (SASI) following an investigation, leaving Olympic champion Kyle Chalmers with a coaching change just 140 days out from the Paris Games.

In a statement provided to the ABC by SASI, a spokesperson confirmed Bishop has been moved into another role until December and said it had “received information that has resulted in an investigation”.

“Following this investigation, SASI can confirm that Craig Stewart has been promoted to the role of Head Coach, with Peter Bishop reassigned into a role focused on developing talent and strategies as SASI aims to maximise success during the 2028 and 2032 Olympic and Paralympic Games cycles,” the spokesperson said.

No details of the investigation were released.

Swimming Australia has revoked Bishop’s coaching accreditation until the end of the Olympic cycle.

In a statement, the sport’s governing body revealed it had been “informed of a recent investigation and findings by the South Australia Office for Recreation, Sport and Racing into South Australian Sports Institute (SASI) high-performance swimming program”.

“Swimming Australia respects the process and findings and has revoked Peter Bishop’s coaching accreditation until the end of the Olympic cycle, upon which he is eligible to reapply,” Swimming Australia said.

The ABC has reached out to Bishop for a response.

Stewart has been Bishop’s assistant, working at SASI for more than six years.

He was named the 2022 SASI coach of the year, and it is believed he was told on Tuesday of the investigation outcome.

“Swimmers in the SASI program remain focused on their goals this year and continue to prepare for their upcoming events in a world-class program,” a SASI spokesperson said.

As well as guiding Chalmers’ career, Bishop also coached backstroker Hayden Stoeckel, who claimed world championship gold in 2007 as well as Matt Cowdrey, who collected 13 golds across three Paralympic Games.

Chalmers won gold in the 100-metre freestyle at the 2016 Rio Olympics and silver in the same event in Tokyo.

He is the reigning world champion in the 100m freestyle after his victory in Fukuoka last year and one of Australia’s gold medal favourites for Paris.

Chalmers, 25, was also named the 2023 SASI male athlete of the year.
