Ireland will play both South Africa and Australia next year in One-Day International fixtures.
The games will both take place at Benoni in South Africa, with Ireland playing the hosts at Sahara Park, Willowmoore on Sunday, September 25.
They will then face the touring Australians at the same venue two days later on Tuesday, September 27.
“It’s fantastic news for Irish cricket.” said head coach John Bracewell.
“These are exactly the type of fixtures Irish cricket needs to take the game to the next level.
“There are fewer tougher challenges than playing South Africa in their home conditions plus the number one ranked side in Australia.
“The players will all relish the challenge and allied with the home fixtures already confirmed against Pakistan and Sri Lanka, we are seeing a much needed increase in the volume of top class cricket that we need.”
