Marriage matters to Australian society and it matters to many couples regardless of gender. It’s great that we have civil unions and same-sex law reform. However, they still fall short of full Constitutional equality. Only marriage can achieve that. Many parents and grandparents realise they may have gay children or grandchildren today or in the future. No one wants second best for their child. We all want our children to be able to grow up with the same aspirations and chance for love and happiness.
