Waring was quoted at the time by The Daily Mail saying she had been "f***ed around" in the separation.
Despite the painful split, Waring is now showing a strong public face.
Her Friday Instagram hinted at the milestone moment her split from Lyon became public knowledge, while also looking to her family's future with optimism.
"My little tribe, a year on," she posted on Instagram with a photo of her daughters.
"We might not be the family we once were but the girl gang is stronger then ever and can't wait for our new adventure next year!"
The Aussie cricket team's WAG fraternity rallied around Waring on Friday with a series of public messages of support.
Aussie cricket WAG Candice Warner, the wife of suspended Aussie cricketer David Warner, was among the first to reach out to Waring on social media.
'So good!!' she wrote with a love-heart emoji.
Usman Khawaja's wife Rachel also shared a warm message for Waring and her family.
"So much love for you beautiful girls,' she wrote.
Waring revealed recently she has lost more than 20kgs since the separation after finally finding time to start a new diet.
She revealed to The Herald Sun in March there were times during the break-up she simply wanted to "curl up in a ball" and hope the whole mess would go away.
"It's very hard to switch off an emotion so strong," she said.
"He was my first love and it's hard to understand how you can love someone for nine years and then they become someone you don't recognise," she said.
"I'm sure everyone would have completely understood if I decided to switch off and curl up in a ball.
"I had a choice on how I wanted to present myself to the world and get through things.
"I just wanted to show my girls that I can and will get through anything as a strong woman and that happiness isn't defined by a man — as much as it hurts to lose him."
Lyon and McCarthy are still dating, according to recent reports are "very much in love".
McCarthy a Perth-based real estate agent is a former flame of Lyon's Aussie cricket teammate Mitchell Marsh.
She is reportedly overseas for the summer and has not yet made an appearance at one of the Aussie team's Test matches against India this summer.
She missed Lyon's starring role in Australia's 31-run loss to India at the Adelaide Oval where the off-spinner starred with the bat and ball.
