My understanding is that Dick Smith foods has been sold to Sanitarium. A nice little earner for Mr Dick, to be sure. And good on him for having a go - that's business, after all.
Unfortunately, for all of Dick's bleating about why we should buy Australian, Sanitarium is not 100% Australian owned!
Sanitarium is owned by the Seventh Day Adventist Church who, due to their not-for-profit-status as a religious organisation, don't pay any taxes.
