After his TV stint and break up with his former girlfriend, McLeod, Agnew chose to step away from the spotlight to help "put himself back together."
During an interview with Herald Sun in November 2020, he admitted that it was a calculated move on his part to stay low profile.
I did not come out of both the show and the relationship in great shape and I needed time with my close friends and family to pick myself up and put myself back together, really.
However, the heartthrob added that he had no regrets about taking part in the dating show and not finding a lasting girlfriend. Instead, he felt he found an opportunity to continue to talk about science to a broad audience.
In February 2020, he had briefly returned to the spotlight to present his science show, Dr. Matt Agnew's Guide to Life Beyond Earth, at the Adelaide Fringe Festival. His show was about the wonders of the solar system.
