Toohey and his brother James Matthew ran pubs in Melbourne (The Limerick Arms and The Great Britain) before moving to Sydney in the 1860s.

They commenced brewing Tooheys Black Old Ale in a brewery in the area of present-day Darling Harbour.

Due to the significant discriminatory and protectionist financial impacts that they faced, Castlemaine Tooheys successfully invalidated the law.

As of 2015[update], the Tooheys brand also was the major sponsor of rugby union in New South Wales and Queensland.
