Internet trolls have defaced a Facebook site paying tribute to the victims of the Queensland floods.



Images of bloodied dead babies and pornography appear in the photos section of the "R.I.P Families who lost members in the Toowoomba Flood" page.



The images have been described as "sickening" by the dozens of people who have visited the page to pay tribute to victims.



"There are some sick people in this world," writes Ash Martin.



"Honestly, who gets their kicks out of posting sick photos and comments on tribute pages?"



Another Facebook poster James Benson said it was unAustralian.



"The people or person that has posted those utterly sickening photographs should be ashamed to call themselves Australian, and if they're not, they should leave this country alone. People have died and more are missing you twisted good-for-nothings!"



The Facebook page contains dozens of tributes to those killed in the floods.



Tracey Hoch wrote she could not describe how sad she was feeling.



"My heart is breaking for you all up there," she said.



Emma Gordon wrote: "RIP to those poor people who lost their lives thinking of their families."



In November, Facebook pages paying tribute to two dead teens Cameron Lowe, 17, and Chantelle Rowe, 16, were defaced.



One of the people behind the defacing was reportedly a high-ranking member of the Ku Klux Klan in the US.



Federal Communications Minister, Stephen Conroy said sites such as Facebook had responsible use policies and the government expected them to be enforced.



Comment was being sought from Facebook.
