In all, over a five-year period, there were 737 redundancies, a further 866 resignations and 203 retirements, but the total number of staff only fell by 313 due to the ABC hiring 650 staff over that period. In June 2021, the ABC announced its plan to move around 300 staff to offices in Parramatta, in a plan which would see 75% of journalists and producers moving out of the Ultimo building by 2025 in order to reduce costs. Rental from some of the vacant space in the city centre would earn additional income to offset the ongoing effects of the significant funding cuts since 2014 and the recent indexation freeze.

On 19 October 1974, the Lissajous curve design experienced its first facelift with the line thickened to allow for colour to be used. It would also be treated to the 'over and under' effect, showing the crossover of the line in the design. To celebrate its 70th anniversary on 1 July 2002, the ABC adopted a new
