Newly married couple John Luke and Mary Kate, the newest Mr. and Mrs. Robertson from the "Duck Dynasty" family, headed off to Australia to enjoy their honeymoon.

The happy couple shared several photos of their honeymoon on their social media accounts. John Luke shared on his Instagram account (@young_and_beardless) a photo of the two of them feeding some kangaroos and wrote, "Hello mate!"

Meanwhile, Mary Kate shared on her Instagram account (@marykaterob) two photos—one showed her cradling a goat and the Little Duck Wife wrote, "Australia, I really do love your koalas, but I really really love your goats!"

In the second photo, the newlyweds were seen reaching out for each other with a two-ball statue in between them. "Oh hey there JL!" Mary Kate simply wrote beside it.

Before the two got married, John Luke and Mary Kate received some sage marriage advice from another "beardless" member of the Robertson clan—Alan, who is a retired pastor of White's Ferry Road Church of Christ in West Monroe, Louisiana.

"In your relationship with one another, have the same mindset as Christ Jesus," he told them.

Alan shared his pearls of wisdom to the young couple in an e-mail to the Christian Post. "My advice is to be honest with each other and always be prepared to forgive offenses because there will always be plenty of opportunities for that," he further said.

"If a couple can live out the challenge Paul made to the Philippian church in Philippians 2:3-5, they will do well. Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of others."
