Jackman was trying to repel from the top of the Sydney Opera House onto the stage on Tuesday when he hit the brakes too soon and smacked his face on a lighting rig.
The actor got bandaged up and continued with the interview.
He said the stunt was "so much fun until the end."
/*Oprah*/ flew 300 of her fans to Australia for an eight-day ultimate adventure that included sailing with actor Russell Crowe.
The trip began last week and will end with two taped shows.
The "O-vasion" will collectively cost the Australian government $5 million. However Oprah's exposure, so far has raked in $38 million for the economy.
