Weet-Bix is a whole-grain wheat breakfast cereal created and manufactured in Australia and New Zealand by the Sanitarium Health Food Company, and in South Africa by Bokomo.

Osborne set out to make a product more palatable than Granose, a biscuit that was marketed by the Sanitarium Health Food Company at that time.

Macfarlane suggested that they ship the product to New Zealand, where it proved so successful that it became difficult to adequately supply the market from Australia.

All shares in the company were specified to be under the control of the directors, the first of whom were Bennison Osborne, Malcolm Ian Macfarlane, Alfred Richard Upton and Arthur Stanley Scrutton.

In 1933, Macfarlane left the company to pursue other business interests, leaving Osborne as the sole managing director.

However, the venture was unsuccessful, and Weetabix eventually entered the US market from Canada via Clinton, the site of the original US factory.
