The 15-year-old said the pair will have koalas, some bigger animals and he joked there might even be crocodiles - something that would no doubt have made their 'wildlife warrior' late dad Steve very proud.

"Yes, there are going to be animals at Bindi's wedding, it's going to be very exciting," Robert said.
"She definitely wants koalas walking down the aisle and I think we're going to incorporate some larger animals as well."
He added with a laugh: "And maybe some crocodiles!"

Bindi, 21, also recently revealed that she will be walking down the aisle with a koala.
Speaking on Good Morning America last month she said: "I'm not sure how many people have walked down the aisle with a koala," she said.
"But we may be setting some new trends for weddings from here on out!"
