Swedish actress Alicia Vikander is reportedly dating her The Light Between Oceans co-star Michael Fassbender.

The two had filmed parts of The Light Between Oceans in Australia. Fassbender, 37, was photographed with the 26-year-old actress at Bondi Beach in Sydney. German-born Fassbender went surfing, and then joined Vikander on shore for a meal.

The Light Between Oceans is based on the 2013 novel by M.L. Stedman, and is set for release in 2015.

Here is the synopsis:

After four harrowing years on the Western Front, Tom Sherbourne (Fassbender) returns to Australia and takes a job as the lighthouse keeper. To this isolated island, where the supply boat comes once a season, Tom brings a young, bold, and loving wife, Isabel (Vikander). Years later, after two miscarriages and one stillbirth, the grieving Isabel hears a baby’s cries on the wind. A boat has washed up onshore carrying a dead man and a living baby. The couple keeps the baby, and name her Lucy.

When they eventually go to the mainland, they discover that a woman (played by Rachel Weisz) has been searching for her lost husband and child.
