Queensland teenager Alyssa Azar has made it back safely to base camp after becoming the youngest Australian to climb to the summit of Mount Everest.
The 19-year-old, who reached the summit of the world's tallest mountain on Saturday, said she'd made it back to safety on Monday.
"Thanks everybody for your messages of support, I am now back safely in Base Camp after an amazing climb and successful expedition," she wrote in a Facebook post.
The Toowoomba teenager achieved her goal of conquering Everest on her third attempt, after her previous two efforts were thwarted by an earthquake and an avalanche.
In doing so she broke the Australian age record set by 21-year-old Rex Pemberton who climbed to the summit 2005.
Her trainer, Chase Tucker, has described Alyssa's training regime for the expedition as equivalent to that of an athlete training for the Olympics.
"She's an incredibly disciplined athlete," he told AAP.
Former Olympian and Commonwealth Games swimming champion Lisa Curry was among those quick to congratulate the young adventurer.
"I can breathe again now!! Been thinking of you a lot. I'm so proud of you and all your years of training and efforts, ups and downs," she posted.
"Your journey to the top of the world is truly amazing."
But Alyssa's father and biggest cheerleader Glenn has not been available to comment because he is leading a group along the Kokoda trail, though he has been in contact with his daughter via satellite phone where possible.
Alyssa had taken along a photo of her autistic 12-year-old brother Christian to leave a picture of him at the summit.
News of Alyssa's successful climb came at the same time as confirmation of the death of 34-year-old university lecturer Maria Strydom, who died while climbing on Everest on the weekend.
