They do not make it any more. Here is the response I received.
"We are really sorry not to be making this product any more, unfortunately when both Woolworths and Coles decided to remove Blast to sell their own brands it made it unviable to continue making it. We don't have any stock left at all I am sorry."

I'd suggest you try another Natures Organics product Kevin - from the Earth Choice range. More bubbles than Blast and much less concentrated, but still much better than the top selling commercial brands.

Earth Choice dishwashing liquid is rubbish. The Choice Consumer Review rates it the lowest with some claiming it "less effective than warm water".
