Buy Lye in Tasmania

Hi,

I was searching the net to find a place to buy lye for baking pretzels, when I found this site. There is a forum topicon this already, and I have tried to contact, forum member 'makebread' but no luck. So I wonder if anyone knows of a place to buy food grade lye in Tasmania, preffereably around Lauceston. Any help would be appreciated.

Cheers,

Sam
