Stage III, the interiors, started with Utzon moving his entire office to Sydney in February 1963. However, there was a change of government in 1965, and the new [[Robert Askin]] government declared the project under the jurisdiction of the Ministry of Public Works. Due to the Ministry's criticism of the project's costs and time,<ref>{{Cite web|url=http://www.sydneyoperahouse.com/About/The_Architect.aspx|title=Sydney Opera House – the Architect – Sydney Opera House|website=www.sydneyoperahouse.com|access-date=10 May 2016|archive-url=https://web.archive.org/web/20160513175048/http://www.sydneyoperahouse.com/about/the_architect.aspx|archive-date=13 May 2016|url-status=dead}}</ref> along with their impression of Utzon's designs being impractical, this ultimately led to his resignation in 1966 (see below).

The cost of the project so far, even in October 1966, was still only [[Australian dollar|A$]]22.9&nbsp;million,<ref>[http://www.sydneyarchitecture.com/ROC/QUA01.htm Sydney Architecture] {{Webarchive|url=https://web.archive.org/web/20070927010222/http://sydneyarchitecture.com/ROC/QUA01.htm |date=27 September 2007 }}.

The second stage of construction was progressing toward completion when Utzon resigned. His position was principally taken over by [[Peter Hall (architect)|Peter Hall]], who became largely responsible for the interior design. Other persons appointed that same year to replace Utzon were E. H. Farmer as government architect, D. S. Littlemore and Lionel Todd.

Following Utzon's resignation, the acoustic advisor, Lothar Cremer, confirmed to the Sydney Opera House Executive Committee (SOHEC) that Utzon's original acoustic design allowed for only 2,000 seats in the main hall and further stated that increasing the number of seats to 3,000 as specified in the [[brief (architecture)|brief]] would be disastrous for the acoustics. According to Peter Jones, the stage designer, Martin Carr, criticised the "shape, height and width of the stage, the physical facilities for artists, the location of the dressing rooms, the widths of doors and lifts, and the location of lighting switchboards."<ref name=autogenerated4>page203</ref>
