In recent years, Sam has made headlines following his divorce with Phoebe, after five years of marriage. The two co-parent their two children Poppy and Billy together.
Sam drew attention again in February this year, after he was found guilty of intimidation against Phoebe's father Mitchell Hooke. However, that decision was later overturned in the New South Wales District Court.
In May, Sam pleaded guilty to three traffic offences, including driving with traces of cocaine in his system.
The trailer also featured Brynne Edelsten, where she confessed: "I am more than just Geoffrey's ex-wife."
"I'm not a gold digger - I can get through anything," she added.
Former Home and Away star Dan Ewing was also filmed in the trailer as he ran down the side of a steep cliff, as well as tennis champion Alicia Molik as she ran through the wilderness.
