Experiential agency Traffik transported 40 tonnes of sand to Sydney Opera House to help Oz Lotto celebrate its 20th birthday on Australia Day.
Oztralia Beach was created for a beach party that was free for anyone who wanted to attend.
Adam Harriden, creative lead at Traffik, said: “It was incredible to combine the two most important things in Australia, on Australia Day.”
Kent Madders, brand manager at Oz Lotto, added: “NSW Lotteries has a proud history with the Sydney Opera House which dates back to 1957, when tickets in the first Opera House Lottery draw went on sale to fund the construction of the landmark.
“To be able to offer this unique experience of Oztralia Beach, a first of its kind, was just incredible.”
