The events were originally scheduled to kick off next month.
The 2020 Under The Southern Stars festival has been postponed to next year "light of the current global health crisis".
The festival, which was to feature performances from LIVE, Bush and Stone Temple Pilots, was scheduled to kick off next month. However, it has now been moved to early 2021.
"Producing Under The Southern Stars music festivals each summer is a privilege and our fans and patrons have become part of the family," promoter Andrew McManus said today.
"In light of the current global health crisis, we feel that it is imperative to protect the Under The Southern Stars family and proceed in a clear and calm manner.
"We have been closely monitoring the situation as it develops and following directives from the Chief Medical Officer of the Australian Health Protection Principal Committee (AHPPC). With the increase of travel bans and lock downs, in an effort to stop transmission of the virus, and with the safety of our patrons, artists, staff and crew in mind we have no other alternative than to postpone our April 2020 festival tour dates.
"We’ve been in consultation with all UTSS2020 artists in regard to their touring schedules and we plan to announce revised festival dates for Under The Southern Stars next week. It is expected that our festival will be postponed until February/March 2021.
