Star Trek star William Shatner is heading Down Under and wants to "dive with whale sharks in Perth".
Shatner, famous for playing James T. Kirk, captain of the USS Enterprise, will be jetting to Australia in March for two Star Trek conventions and the 81-year-old and his wife, Elizabeth Anderson Martin, have allotted plenty of spare time for sightseeing.
Shatner wants to dive with whale sharks at Ningaloo and visit opal mines in Coober Pedy, however the couple have a few other days free.
He would love to hear from Australians, via his Twitter account @WilliamShatner, about where they should explore.
"We have about a week," Shatner told AAP while promoting his new family animated film, Escape from Planet Earth, in Los Angeles.
"If you have a suggestion, let me know."
Shatner will be feted by Trekkies next month at the Oz Comic-Cons in Perth and Adelaide.
"In between I'll just discover Australia," he said.
"I have a hunk of time that I'm going to spend in Australia. I'm trying to judiciously apply myself."
The Canadian-born star of Boston Legal and TJ Hooker beams when he talks of his love for Australia.
It was Australia where, in 2011, he debuted his one-man stage show, which became such a success he took it to Broadway.
"I am so deeply involved with Australia and the beauty," the octogenarian, who has no plans to slow down, said.
"I want to dive with whale sharks in Perth.
"I want to go see some of those strange rock formations in the centre.
"I want to go to the opal mines in Coober Pedy."
On a previous trip he enjoyed a magical moment lying on his back in Tasmania at sunset and listening to wallabies jumping through nearby bush.
"You could hear it," he excitedly said.
"Unbelievable the sound.
"And I sang Waltzing Matilda. It was mystical."
Shatner will also be spreading the word about Escape from Planet Earth, the family animated film directed by an Aussie, Callan Brunker.
Shatner voices General Shanker, a ruthless military man with a plan to destroy all aliens in the universe.
Ricky Gervais, Sofia Vergara, Jessica Alba, Brendan Fraser and George Lopez voice aliens and other characters in the movie, which opens in Victoria and Queensland on March 28, NSW/SA April 11 and WA on April 18.
"Let me tell you this. Australia is going to love this film," Shatner said.
"This is a film designed to entertain six-year-olds and 12-year-olds and the rest of the family."
