"We welcomed our newest family member Isla Rose Warner at 10:30pm late last night," Warner said in an Instagram post.
"@candywarner1 was absolutely amazing. Mum and Bub doing very well and her big sisters are over the moon."
The lovely couple has been blessed with a third child; now Warner has three daughters under the age of five, with Candice having previously given birth to Ivy-Mae and Indi-Rae in Australia.
Warner returned to international cricket after serving a one-year ban for his involvement in the infamous ball-tampering scandal in South Africa. The unwanted pressures of that controversy saw Candice suffer a miscarriage soon after the South Africa tour.
Warner has previously spoken about the importance of his family during his year-long ban from international cricket.
"I just love being a father. I've got a great, supportive wife, a great family base at home as well. We've got great support around us, the guys here have been fantastic, they've really got around me at this important time for my family," he said.
