Isla Fisher, Olivia, Elula, Sacha Baron Cohen Pictures in Australia

Sacha Baron Cohen and Isla Fisher arrived at the Sydney airport yesterday with their daughters, Olive and Elula. The family is in Isla's home country following a stint in NYC, where Sacha shot his new movie The Dictator. Isla also logged time on the set of Bachelorette with Kirsten Dunst and James Marsden. In addition to giving Olive and Elula a chance to say hello to their Fisher relatives, the Cohen-Fishers' time Down Under will allow Isla a chance to meet up with the cast of The Great Gatsby. Isla was in character as Myrtle Wilson back in August, but production on the Baz Luhrman adaptation of the classic Fitzgerald book has continued in the months since for her costars Leonardo DiCaprio and Tobey Maguire. Newly single Leonardo DiCaprio has been in Australia working and dealing with his breakup from Blake Lively. He might not be single for long, though. Leo's already linked to Alyce Crawford, a 20-something who's appeared on Australia's Next Top Model.
