A speaking tour from the son of the former US president Donald Trump has been delayed, the tour promoter announced on Wednesday.

Donald Trump Jr was to speak at events in Sydney, Brisbane and Melbourne, kicking off this Sunday. However Turning Point Australia announced on Wednesday that “due to unforeseen circumstances” the appearances would be postponed.

“Ticket holders are urged to hold onto their tickets, with details of the rescheduled date to be confirmed in the coming days,” the announcement said. “Ticket holders will be contacted directly … with details.”

In a Facebook post on Wednesday, Turning Point Australia wrote, “It seems America isn’t the only country that makes it difficult for the Trumps.

“Hold onto your tickets, this is a short delay nothing more #CancelCulture.

“Apologies for any inconveniences especially those who had long travel plans.”

Tickets for the events ranged in price, including $89 tickets, $295 for a meet-and-greet, and up to $2,500 for a private dinner.

The tour was also to bring Brexiter Nigel Farage to Australia. The Liberal senator Alexander Antic was another scheduled speaker.
