[1][6][7] Established in 1921, the factory and surrounding model village estate marked Cadbury's first business expansion outside the United Kingdom.

Initially set up to meet the growing demand for Cadbury products in Australia, the factory became a significant part of the Tasmanian economy.

With a water frontage of 8.0 kilometres (5 miles),[9] the location inspired the company phrase "By mountain and sea", which the factory used on a range of promotional materials highlighting the business' interest in maintaining a healthy lifestyle.

[16] Designed by architects Hutchinson & Walker, an additional three-story building measuring 100 metres (340 ft) in length was erected in 1939 at a cost of £A40,000.

[4] Today, the Cadbury's Estate has a rich history with eighteen heritage-listed buildings located on the site, including the former Claremont Primary School.

With frontage along Windermere Bay, the new Claremont School was completed on the Cadbury's Estate in 1924 to facilitate factory worker's children.

In 2021, a $200m development on the site called the Windermere Bay Precinct was proposed, featuring 315 apartments and townhouses, a childcare centre, local shops, a cafe, and a gym and pool within the parkland setting.

The tour also included an inspection of the factory's pure granite conching machines dating back to the 1950s, industrial machinery and wrapping process, ending with a taste-testing and the collection of free samples.

The tours were discontinued in 2008 due to health and safety regulations adopted by the company globally and replaced with a newly built visitor centre at the site in 2010.

[33] During the 2013 federal election campaign, then-opposition leader Tony Abbott offered a $16 million grant to develop and upgrade the visitor centre.

[35] During the 2024 Tasmanian state election, Premier Jeremy Rockliff pledged a $4 million grant for a chocolate-themed park accessible by ferry.

The initial grant supported tourism entrepreneur Simon Currant's vision for a "chocolate experience" at Cadbury, with up to $12 million of state funds available if key project milestones are met.

[note 1] In April 2009, Cadbury Australia announced its commitment to Dairy Milk chocolate blocks achieving Fairtrade International certification by Easter 2010.

In 2016, Mondelez International discontinued Cadbury Dairy Milk's Fairtrade certification in favour for the Cocoa Life program.

[41][42][43] In September 2022, Cadbury Australia announced that all future Dairy Milk varieties would be wrapped in 30% recycled soft plastic, replacing former single-use packaging.

[48] Cadbury have sponsored the Tasmanian T20 franchise cricket team, the Hobart Hurricanes, since the 2018–19 Big Bash League season.

[49] The high levels of sugar killed off bacteria in the plant that break down and treat waste, causing biological sewage treatment to be ineffective.
