In February 2016, he welcomed his first of three children, a daughter named Ev.
In the past, he told News.com.au that he met the mothers of his first baby, Kris and Jane, at an LGBTI event in 2012 and they "just clicked."
While Dave has no romantic relationship with either of the mothers, he has a mutual understanding with the couple and is constantly posting snaps on Instagram in celebration of having a "rainbow baby."

He has since fathered another daughter with the couple via sperm donation, who was born in 2017.
The same year his daughter Bonnie was born to a single mum named Amy, who Dave had also donated sperm to.
Dave, who is the youngest of 11 children, told Woman’s Day at the time: “it’s in my blood to breed” and admitted he had considered becoming a sperm donor for 20 years.
The doting dad opened up about his unique family to The Daily Telegraph last year and revealed he was still single.
“We have this amazing family where I'm an integral part of their lives and it negates the need for chasing a husband,” he explained.
“But you never know, I'm still one of those blokes who's looking and hoping and waiting (for the one).”
