The former mining engineer announced she is expecting her first child with husband Michael Hoskin on 60 Minutes earlier this year.
The bushfire survivor is due to give birth to her first child in December, revealing to 60 Minutes that she discovered she was expecting a few days before she was due to fly to Mt Everest.
She told Hoskin while he was brushing his teeth. 'I just walked in and I left the pregnancy stick there,' she said.
Turia also recently shared a photo of herself to mark the anniversary of the date she was burned in a devastating fire six years ago.
'I’ve never felt compelled to acknowledge the anniversary, but it’s been six years today since I was trapped in a grassfire competing in an ultra marathon. It’s been bloody tough and there's been massive lows, but I’ve managed to rebuild my life and I can honestly say, I’ve never been happier,' she shared.
She added: 'So, this post is for anyone going through a rough patch or a sh*t time - hang in there, surround yourself with good people and never lose hope for your future.'
