However, according to Woman's Day magazine, Russell Crowe has already offered up his estate in Nana Glen on the north coast of New South Wales.
A source told the magazine: "He has a chapel there, and he would be so proud for it to be the place Bindi marries Chandler. He loves Bindi like a daughter".
Crowe's estate is a five-hour drive away from Australia Zoo and provides far more privacy, spanning hundreds of hectares and with the capacity to sleep around 150 people in numerous cabins and houses.
Meanwhile, New Idea claimed Crowe may be tipped to walk Bindi down the aisle, however Bindi has already said her brother Robert will have the honour.
She told Entertainment Tonight; "It'll be really important that Robert walks me down the aisle, that's something that I really want to do. I think that's what dad would have wanted as well."
