My Kitchen Rules couples in dark on final dinner winner KNIVES OUT: My Kitchen Rules grand finalists Jake and Elle Harrison and Steph and Dan Mulheron. IT'S the best kept secret on Australian television. With two different endings filmed for tomorrow night's all-Queensland My Kitchen Rules grand final, not even the contestants know who will take home the $250,000 prize. In one of the filmed endings, Sunshine Coast siblings Jake and Elle Harrison are scored higher by the judges for their five-course meal. In the the other, Hervey Bay couple Dan and Steph Mulheron receive top marks. Most reality shows film their final episodes shortly before they go to air. The Block and Australia's Got Talent filmed winner announcements within 24 hours of them airing. Most recently, MasterChef pre-recorded the finale episode up until the winner was announced. Producers then brought back contestants and family and friends, in the same clothes they had worn months earlier, for the live final few minutes. The Seven Network confirmed two endings were shot for the show so only a handful of people within the production team know who the real winners are. Tomorrow night's MKR finale "episodes" were shot before the first episode of this series was aired. TV commentator David Knox, from industry website tvtonight.com.au, said the MasterChef model was the safest for keeping things under wraps. "They film it at midday and keep (the contestants) in lockdown on the site, feed them and entertain them and they aren't allowed to leave the building until it is broadcast," he said. News of the alternative ending comes as the final four reveal their plans for the prizemoney. Dan and Steph, who were living week to week before the reality competition, will use the prizemoney to open a gourmet sausage shop and for further IVF treatment. The pair have been trying to start a family for five years and have had one unsuccessful IVF attempt. The cash prize will give them the financial freedom to keep trying. "At the moment we work hard all year, take a holiday and whatever is left we sort of try to put some money together for the IVF," 30-year-old Steph said. For Dan, the biggest prize he could win would be to become a father. My dream is to open my gourmet sausage shop, Steph to be at home being mum to the kids, work hard all week and come home on weekends and be a family. Gen-Y siblings Jake and Elle Harrison plan to use their experience on the show to pursue their entrepreneurial dreams and open a late-night supper club in Brisbane's CBD. "Think of it as the after dinner mints of dining," Jake said. Recognising the lack of places to go later in the evening in Brisbane, the pair hope to open a venue that has the "Jake and Elle" stamp all over it. Both sets of contestants will hold separate grand final events at Brisbane venues tomorrow night as they wait to find out who will take home the prize.
