Jacco Verhaeren will leave in September as head coach of the Australian swimming team. The 51-year-old Brabander has decided to return to his family in the Netherlands.

Verhaeren has worked in Australia since 2013 and had a contract until after this year's Olympics. He has decided not to extend his stay now that the Tokyo event has been postponed for a year.

"I definitely considered renewing my contract, but I can't compromise in a top sports climate, nor want to compromise with my family," Verhaeren said in a statement Wednesday.

The Dutchman was commissioned in 2013 to make Australia a top country again and it worked. For example, the country finished second in the medal mirror at the 2015 and 2019 World Cup long track. Ten medals were won at the 2016 Games, three of which were gold.

According to chairman John Bertrand, Verhaeren has given Australian swimming a lot. "He has made his mark with the achievements that have been made. His constant search for development and his curiosity have taken us to a higher level."

In the past, Verhaeren worked as a coach for the Dutch swimming federation KNZB as a coach with the Olympic titles of Pieter van den Hoogenband, Inge de Bruijn and Ranomi Kromowidjojo.
