thorpedo water?

i always knew that ian thorpe or "so-pu" was big in japan, but i never expected this.

now you can buy "thorpedo bottled water"
the ad on tv shows the so-pu swiming around and saying
"you cant change others but you can change yourself"

apparently the water is low GI

i did a bit of a web search and came up with this website thorpedo foods

is this already on sale in australia?
