While 18th birthdays are usually wild affairs, this takes it to a whole new level.

In a nod to her recent victory on the US show Dancing with the Stars last year, Bindi's birthday was themed 'Camping with the Stars' and included a tee pee and campfire cake and thousands of delighted fans.

Crowds queued for up to two hours at Australia Zoo on the Sunshine Coast for the chance to get an autograph and a selfie with Bindi.

Dressed in conservation T-shirt, jeans and Converse sneakers, Bindi arrived standing in the front seat of an open-topped jeep, waving to the crowds.

She was joined by her mother Terri, younger brother Robert and US wakeboarder boyfriend Chandler Powell, who had jetted from the US to celebrate the day with her.

Fans presented her with gifts and handmade cards through the barricades as she strolled beside them on a pink carpet.

Powell posted a gushing message to his girlfriend of 12-months, accompanied by a portrait of them together.

Happy birthday to the most amazing person I know. I'm amazed by everything you have already achieved and I can't even begin to imagine everything you'll accomplish from this point on. I'm very blessed to have you as such a huge part of my life and I'm beyond thankful you've let me be a part of yours. I hope today is as amazing as you are☀️

The Irwins also spent time in the Crocoseum showcase, feeding giant crocodiles meat in front of an elated crowd.

Video messages were played from friends over the loudspeaker and Bindi gave a speech to the crowd, thanking her mum "for giving birth to me". She also took to Instagram to thank her family for their love and support.

Hello lovelies. Well today marks 18 years of life for me, here in Australia and I really don't know where to begin in thanking so many people for an unforgettable journey so far. So I think that I'll start here, with this photograph. This photo was taken within the first year of my life. To be perfectly honest life has changed in a million ways since this photograph was taken. Along the way we gained another incredible part of our family, my brother Robert. Our conservation work with Wildlife Warriors took off around the world. Our home, Australia Zoo continued to expand and has become the greatest zoological facility on planet earth. Our Dad, Mum's soulmate and a superhero for us all, passed away. However, since this photo was taken, 18 years ago, one life ingredient has remained, unchanged, unbreakable. That is the unconditional love that is shared between my beautiful little family and the loyalty we have to eachother and everyone else who has taken this journey with us. I don't think that when this photo was taken even my beautiful parents could have known what life would evolve. I know that I am endlessly grateful for the love and light I have been given since Day 1 of my life.

....leading on from my last post, I have so much happiness in my heart for the journey to come. Being 18 and embarking upon my adult years, I can't predict what life will have in store for me. All I know is that I will try my very best to make a difference in this world with each moment that I'm given. Life is constantly evolving and I'm determined to find the light and love around every corner and share this with everyone who is a part of my story. Thank you so much to every single soul who took the time to read these last two posts, it means so much. I can't wait to see what is yet to come.
