"First of all, what we're trying to do is make a point to the Government that this is ridiculous, why a 130-year-old Australian business needs to move its website offshore just to compete," Grover told .

"The major point of this is making the point to Government that both the parallel importation laws and the GST are currently putting Australian booksellers out of businesses."
