During the gold rush in Victoria, brothers Leonard and George Parsons left England and began manufacturing under the name John Bull Oats in Melbourne.

[3] On 23 May 2006, Nestlé announced its acquisition of Uncle Tobys Australia—in addition to the brand rights in New Zealand—for the total sum of $890 million Australian dollars.

[1] In its corporate supply chain, Uncle Tobys exclusively utilises suppliers who have been certified as “Level A” by the National Association of Sustainable Agriculture.

[9][non-primary source needed] Monro et al. (2003) conducted research on three of Uncle Tobys oat bars[10] (Break-Free Fruesli, Whole meal Fruit, and Chewy Muesli).

"[11] On 26 November 2015, Uncle Tobys was fined $32,400 for false claims about the protein content in oats,[12] after being warned three times by the ACCC in infringement notices.

[13] The commission issued infringement notices because it had reason to believe that Cereal Partners Australia had violated Australian Consumer Law by misrepresenting the protein content within Uncle Tobys oat products.

The commission alleged that the packaging “made false or misleading representations that the oats in these Uncle Tobys products contained a significant amount of protein, which is not the case”.
