Water polo is one of sports great spectacles. But when you combine two fierce tribes who are willing to go hammer and tong over 60 minutes of pure adrenalin, then you get something amazing.

Add one of the most picturesque backdrops in Sydney with 500 screaming fans, and you get something even better – DERBY DAY!

On Sunday April 1, National League teams Drummoyne Devils and Sydney University Lions will fight it out in the inaugural ‘Derby Day’ contest, with both the men’s and women's teams competing for local pride at the Drummoyne Olympic Pool.

The day, which will feature Australian Olympic hopefuls, Aussie Sharks Samuele Avallone, John Hahn, Thomas Whalan and Rob Maitland and Aussie Stinger Hannah Buckling, will be action packed with two games of water polo, plus music, food and entertainment.

Event organisers, Drummoyne’s Avallone and Hahn, who were inspired by the thousands that packed out Bondi Icebergs for Water Polo By The Sea at the start of the year, said the concept was a great way to get new fans into the game.

"Look, we wanted to create an event that was similar to Water By The Sea, but was unique to the water polo community of Drummoyne," Avallone and Hahn said.

"Drummoyne is a great place to showcase the sport of water polo and there's no better way than to have a local rivalry to get the public down there and expose them to it.

"The water polo action is also going to be first class with numerous players eyeing off selection in the Aussie Sharks and Aussie Stingers Olympic squads, so if people have never seen water polo before, Sunday will be a good time to start."

With just four months remaining until the London 2012 Games all five Olympic aspirants will use Sunday’s matches and the final rounds of the National Water Polo League to enhance their chances of selection.

Sunday’s fixtures are particularly important with places in the final squads for the London Test Event and FINA World League Preliminaries on the line.

Both teams are also on the cusp of qualifying for the top six in the National League final series with the Drummoyne men currently in sixth just one game ahead of their rivals Sydney Uni.

Gates open for Derby Day at 3pm followed by the women’s National League match at 4pm featuring Drummoyne Devils versus Sydney Uni. The men hit the pool at 5.30pm.
