Zac Efron celebrated his 33rd birthday Down Under.

The “High School Musical” star, who extended his stay in Australia when the coronavirus pandemic hit, threw himself a birthday bash alongside his new girlfriend Vanessa Valladares, reports the Daily Mail.

The couple was joined by radio host Kyle Sandilands, “The Voice Australia” host Renée Bargh, tennis champ Pat Rafter and Craig Hemsworth, father of Chris and Liam.

Last month the “Baywatch” actor was snapped enjoying brunch with Valladares in the seaside resort of Lennox Hill, having just returned from a skiing vacation.

The two are said to have met in July when Valladares was working as a waitress in Byron Bay. She is rumored to have quit her job and moved into Efron’s digs.

The Daily Telegraph reports that Efron put a bid in for a home in the area but missed out. And the Daily Mail reports that he canceled a flight back to Los Angeles and has extended his tourist visa from three months to 12 months.

Efron will have to fly home at some point. He is scheduled to star in the remake of “Three Men and a Baby.”
