Advice for other brands of silicone in Australia

[Mermaid Kate Silverfin]

So I am interested in making my own silicone tail, but as I live in Australia, shipping Dragonskin brand silicone here is incredibly expensive (even through the one local supplier). Since Dragonskin is just a brand, can anyone recommend other brands of silicone that are locally sold with the same quality and properties? Also, what specifically are the properties of Dragonskin that makes it so good for tail making? Not many places seem to include materials data sheets, so it is really hard to compare brands! Does anyone have experience (good or bad) with other brands?
Thanks!
