[94][95] Goodrem also appeared in a documentary special celebrating the anniversary titled Neighbours 30th: The Stars Reunite, which aired in Australia and the UK.

[150] Later on, she embarked on the rescheduled "Hearts on the Run" tour in August and September 2023 that took place in the UK, Ireland, Scotland, Germany, France, Switzerland, Denmark, Norway and Sweden.
