Channel Ten confirmed the news after it was revealed that Ali and Grant's relationship had ended once they left the Bachelor In Paradise experience.
“I have had my heart broken, but I’ve picked myself up and I’m ready to put my heart on the line again. I’m absolutely thrilled to start this new adventure,"Ali said.
“I’m looking for a man who is light-hearted and kind, a genuine and down-to-earth man who will sweep me off my feet and love me for me. And I’m looking forward to offering that love back to him in return.”
Ali, 32, first captured hearts in the inaugural season of The Bachelor Australia in 2013 when she was left heartbroken by Tim Robards.
The Bachelorette starring Ali will air later this year on Network Ten.
