"Duck Dynasty's" John Luke Robertson and his new wife, Mary Kate McEacharn, shared some photos of their romantic honeymoon this week as they explored Australia and Indonesia. 

The newlyweds started their honeymoon in Australia, and John Luke shared a photo on Instagram of them feeding a joey and captioned it, "Hello mate." Another snap shows John Luke leaping on the beach while his wife took in the amazing view. "Island exploring with my woman," he wrote. 

Mary Kate also shared some pictures of their vacation wherein they can be seen snorkeling, jet skiing, and swimming with the tropical fish in Bali. In one photo, Mary Kate is seen reading a book which she captioned, "honeymoon part 2, day 3, trying to up my reading game so I can be on the same level as JL…it's quite a challenge." 

"These past two weeks were an absolute dream! But happy to be heading back to Louisiana," she captioned a last snap of her kissing her husband as they sat on a boat above the blue waters of Bali. The photo was posted on Sunday, July 12. 

Prior to their honeymoon, the "Duck Dynasty" star told Us Weekly that he and his wife were going to the Outback and that he was going to be a groomsman in a wedding on the Fourth of July. He told the magazine that his friend in Australia got engaged a week after he did. 

"I called him to tell him about my engagement and he told me about his and he wanted me to be in his wedding," said John Luke. "So we're kind of killing two birds with one stone." 

John Luke and Mary Kate tied the knot on June 27 at the Robertson family farm in West Monroe. It was reported that the groom's father, Willie Robertson, officiated the ceremony.
