Silicone Breast implants above 1000cc

I am just wanting to find out what companies make silicone breast implants over 1000cc. I currently have 920cc silicone Polytech implants, but am not satisfied with the size. I don't want saline implants. I would possibly like up to 1300cc in silicone. I know the company Sebbin in Europe make custom silicone implants, the largest I've seen from them is 1500cc. I'm unaware if this is something that can be ordered to Australia. I'm basically just wanting to know, if there's any other companies that make bigger silicone that can be ordered here? I haven't spoken about it with my surgeon yet, I am just wanting to know if its possible... Thanks :)
