Relationships Australia became the custodian of Neighbour Day in 2014 and the day has since grown into an ongoing, year round social connection campaign that seeks to address loneliness across Australia. Neighbours Every Day is the evolution of Neighbour Day into a year-round campaign with a dedicated day-of-action named Neighbour Day, celebrated on the last Sunday of March annually. As the leading social connection campaign in Australia, Neighbours Every Day continues to grow and support all in Australia to build respectful and sustainable relationships with those around them.
