The 5-13 January 2018 event will be the first time the tournament has headed to the iconic and pristine costal locale of Geraldton, with WA most recently having hosted the ACCC in the 2010-11 season in Bunbury.
WACA CEO Ms Christina Matthews said: "Cricket has seen some fantastic talent come out of regional WA, so it's important for the sport to take the game back to the country where possible.
"This is a great opportunity for Geraldton to showcase its facilities and for Australia's best male and female country cricketers to showcase their skills.
"We look forward to welcoming all teams to WA and Geraldton in January for what we're sure will be a memorable edition of this tournament."
Cricket Australia Executive General Manager of Game and Market Development Andrew Ingleton said: "The Toyota Australian Country Cricket Championships are a great celebration of country cricket, providing Australia's best regional players with the opportunity to test their skills at a high level of competition.
"Regional areas continue to produce quality cricketers, from the great Sir Donald Bradman to current Australian star Josh Hazlewood, and previous country championships players including Andy Bichel, Michael Bevan and Shaun Tait.
"Last year's Men's Player of the Championships, Ben Pengelley, is now a South Australia rookie and representing the Cricket Australia XI at the JLT One-Day Cup, which highlights the Pathway that exists at this tournament for regional players wanting to push through the ranks of Australian cricket.
"We look forward to taking this event to Geraldton for the first time, and to working with the City of Greater Geraldton and all players, officials and volunteers to ensure this event is a great success."
City of Greater Geraldton Mayor Shane Van Styn, said: "We're over the moon to be named as the host for next year's tournament. It's a massive sixer for us.
"Geraldton is continuing to establish itself as a destination of choice and we have got some runs on the board hosting different events and it's great that we are continuing to attract them.
"This has hit off a great relationship between the City, the WACA and Cricket Australia, and we hope that we can work with them to bring even more exciting cricket events to our region."
