The star, who came third in season six of the reality TV show has since gone on to own his own dog training facility, a service based in Western Sydney, where pet owners take their pups to be trained to behave.
While he is looking a little more mature these days, Dave is currently sporting his long golden locks and a beard to match.
In February 2016, he welcomed his first – of three children, a daughter who for privacy reasons he has not yet revealed the name.
In the past, he told News.com.au that he met the mother of his first baby at an LGBTI event and the two "just clicked."
While they have no romantic relationship, he has a mutual understanding with his daughter's mother and he is constantly posting snaps on Instagram in celebration of having a "rainbow baby."
He has since been a sperm donor to two children.
