Top Moments from the Australian Open: Getty Images

As tennis players from around the world have descended on Melbourne for the annual summer sporting highlight, the Australian Open, Getty Images and Walkley Award-winning sports photographer, Cameron Spencer has been behind the lens in the photography pit for the first week, viewing every volley, backhand and serve close up.

He says: "this year's Aussie Open continues to surprise me, there have been so many upsets this year and it's incredible to be able to photograph these sporting legends.

"For me, the top moments to capture have been the big rallies and emotion between Nadal and Monfils, Wawrinka's powerful backhand, Venus Williams' athleticisim on the court and the catwalk, as well as Serena Williams' playing with her hair out which always makes for incredible imagery. Of course the excitement from the crowds makes this event a highlight for me every year also."
