Dianne Buswell threw her support behind her father after he completed six months of chemotherapy.
The Strictly Come Dancing star, 34, first announced that her father Mark was undergoing treatment last year, breaking down in a video on social media.
At the time, she explained that he had been diagnosed with a health issue and soon after began sharing updates on how he was doing with her followers.
The professional dancer, who met partner Joe Sugg when they competed together on the BBC series six years ago, has now revealed that her father has reached a major milestone.
“To my dad, you made it 6 months later and 12 rounds done,” she posted on Instagram alongside a series of photos and videos of him over the past few months.
'I'm so proud of you it's been a tough road but you've always done it with a smile and a thumbs up. I know you were scared and I know it wasn't easy, but you did it.
'I wish so much I could be there right now and just hug you. You are my hero and you made me realize that we all have much more strength than we think. And to my beautiful mother who didn't leave her side and was the best support system ever, thank you.
She added: “Us kids are so lucky to have you both, we love you so much.”
Dianne then said it was time to book “that trip back to the UK” for his parents, who had to cancel a visit from Australia after he fell ill.
The video ended with a clip of Mark ringing a bell in a hospital ward to mark the end of his treatment.
She was quickly inundated with messages of support, including from her boyfriend's sister, Zoe Sugg, who shared a series of love hearts in the post.
Amy Dowden, who faced her own cancer treatment last year, wrote: 'Argh, I'm crying! So happy for you all! Well done Mark, your absolute hero and to my beautiful friend Dianne, I know how strong you have been and I am so proud of you xxxxxxx Celebrations are in order and a big party when you are in the UK xxx.'
Meanwhile, Mark commented: 'I'm so happy to have such a loving wife and such loving children, my journey with cancer has been difficult. We're looking forward to spending Christmas in the UK, thanks again everyone for your messages of support, love to everyone.'
Sharing her health diagnosis with her followers, Dianne said there was “a little road ahead” for her father, but she believed he was “going to be fine” and that the family would “get through this together.”
Although her family had plans to go to the UK for Christmas last year and watch her compete on Strictly with her partner Bobby Brazier, she returned home to Australia after the season ended.
Dianne had already said that it was “difficult” being so far from home and not being able to support and help her family “in their time of need”.
Strictly Come Dancing is currently streaming on BBC iPlayer.
