Bindi Irwin and Chandler Powell show why they're considered #couplegoals

It's four days before Christmas, but based on Australian celebrity Bindi Irwin’s Instagram page, the countdown could have very well been countdown for Valentine’s Day.

The 18-year-old wildlife warrior has flooded her social media account with photos of herself with her boyfriend, American wakeboarder Chandler Powell. In one post, the “Dancing with the Stars” Season 21 winner posted a couple picture while they were hiking at Carnarvon Gorge.

Bindi captioned the photo, “#Flashback to hiking Carnarvon Gorge with this amazing human. Watching the golden sun dissolve behind the gorge, listening to birds and looking for wildlife. We live in a beautiful world. Where will you be spending Christmas?” Earlier, she also uploaded an image – which has 60,000 likes to date – with them visiting their conversation property.

“Hiking and looking for wildlife is always wonderful especially when you find an adorable wild koala,” Bindi wrote. “Our property was set aside to protect our gorgeous icon species and all the native wildlife in the spectacular bushland near the Great Dividing Range. It is a true blessing to find a little koala curled up in the trees and a great reminder that we have to protect them forever. This photo captured by @RobertIrwinPhotography is so special as this was the first time Chandler has ever seen a wild koala! And what a sweetheart she is. Such an amazing moment. ”

Her 20-year-old boyfriend, meanwhile, commented, “One of those moments I’ll remember for the rest of my life.”

Earlier in December, Bindi posted another photo of them that came with a bittersweet message. “You are flying back to the USA today,” she opened the caption. “Dropping you off at the airport & waving goodbye, it never gets easier. Thank you for the most wonderful adventures these last few months.”

She also shared that she has known Chandler since he was 16. “Every day, from the very first day I met you, you've been my sunshine,” she wrote. “I will see you again soon! Thank you for everything, you always make me smile, no matter how far apart we may be. Have fun while you're away, go find lots of manatees in Florida for me! I miss you so much already. You really do mean the world to me.”

Bindi, who has been included in the top 10 of Maxim's Hot 100 this year, met Chandler back in 2013 when he visited Australia Zoo, on a competition tour. The two stayed in touch and soon enough, their friendship blossomed into a full-blown romance.
