Urban also shared a photo of himself and Kidman kissing on the balcony of their rented Sydney mansion.
“Here come OUR roaring 20’s!!!!” he said, referring to the turn of the decade.
Of course, the couple also brought their daughters, Sunday, 11, and Faith, nine, along for the trip, with Faith celebrating her birthday with family Down Under.
“Our baby girl is now 9! We love you so much precious precious girl. Happy birthday Faith!” proud mum Kidman said of a throwback photo she shared on Instagram.
