Wentworth stars Nicole da Silva, Danielle Cormack, Libby Tanner, and Socratis Otto will not be flying to Chicago next month for a planned Wentworth Con fan event.
The sold-out April event has been rescheduled for late August, with organisers offering ticket refunds.
Other events for Melbourne (mid-June) and New Jersey (early August) are looking at future dates in case these will also be postponed.
The Melbourne event, in partnership with Fremantle, announced only last week, is due to go on sale in mid April.
“We ask that you bear with us as we navigate these extenuating circumstances and promise to do our best to get this resolved as quickly as possible. Most importantly, please stay safe and take care of yourself and your loved ones during this time,” organisers said.
