The celebrity couple, who got engaged last year, took his children 14-year-old Brooke, 12-year-old Jackson and 10-year-old Summer, together with Hurley's 9-year-old son Damian, to Movie World on the Gold Coast.
One onlooker told New Idea magazine: "I don't think they stopped smiling the whole time - they clearly love each other's company. There were a few tempers fraying around us - you know what it's like when kids have to wait in line - but nothing was too much trouble for Warnie and Elizabeth. It was quite touching."
The 46-year-old model and actress reportedly giggled as she watched Warne go on the rollercoasters with the children, later writing on her Twitter page: "Great day at Movie World today. Rides too scary for me - I had to bury my head in my 9-year-old's shoulder."
Simone Callahan, who is the mother of Warne's three children, revealed last year that the cricketer was cynical about her romance with Toby Roberts, saying: "I think [Shane] thought this might have been a relationship that would be all over pretty quickly."
She also admitted that Warne and Hurley's engagement came as "a little bit of a shock" to her and their children, but added: "He can do what he wants."
