AAP photographer Lukas Coch has won the 2018 Nikon-Walkley Photo of the Year prize for his shot of Labor MP Linda Burney.
"Linda Burney Airborne" was taken just after the same-sex marriage bill vote passed on December 7, 2017 and shows the diminutive Ms Burney in a celebratory embrace with Liberal MP and tireless same-sex marriage campaigner Warren Entsch.
Mr Coch says the image is emotional given Ms Burney had lost her son, who was gay, just weeks earlier.
"As a father myself I was just thinking, 'how can she even be here at work such a short time after', but it was really important to her," he said.
"It was a bipartisan and emotional moment that was very nice to see.
