Australian Lamb is back. This year, the hotly anticipated summer campaign is skewering the generation gap that continues to divide the nation.

Co-directed by Trent O’Donnell and Aimée-Lee Xu Hsien – a Gen X-er and a Millennial, respectively – the film imagines a world in which the generations have been separated by The Generation Gap: an impassable chasm that keeps each age group away from the others.

Left to their own devices, each generation has become the worst version of themselves – until a lamb BBQ appears to remind Australians of all ages that, actually, we have plenty in common.
