Grand slam champion Samantha Stosur has hinted that tennis stars may try to boycott Margaret Court Arena at next year's Australian Open.

Stosur is passionately backing Casey Dellacqua in her stance against Margaret Court after the legendary 24-times major winner created a firestorm with her public opposition to same-sex marriage.

Even the Prime Minister was dragged into the debate after calls to have Court's name removed from venue named after her at Melbourne Park.

Dellacqua - who has two children in an openly gay relationship with former touch football champion Amanda Judd – has received almost 8000 retweets of her post: "Margaret. Enough is Enough."
