Is it real or a scam ?

On 10th of April , I received an e-mail message sent by Carol Sweet using the Austaralian Lottery Inc informing me that my e-mail won 4OO,ooo,oo four hundred thousand Dollars , but I have to claim through a Nigerian Agent office named Williams Frank because there's no representative for me in Europe. I contacted this agent through a message and he asked me to fill in informations and i sent him without official doents. Next, an other e-mail from first bank in Plc Ninubu Square in Lagos contains Two Faxes and telephone number and signed by Dr Jone Williams as the director . He said that the International Lottery of Australia has sent him the form of winning and approval to transfer if I send an amount of 480 Dollars as fees and I didn't do. I want from The real Lottery of Australia to give the answer with the help of friends all over the world in order to free ourselves from scamming. Thanks a lot.
