One Plus One premiered in 2010 with the launch of the ABC's 24-hour news channel. The original program was hosted by Jane Hutcheon, and featured ten-minute interviews with guests, with one of the interviews conducted by Hutcheon and the other two conducted by other ABC journalists. In 2012 the format changed, with the interviews extended to 28 minutes long and all conducted by Hutcheon. This format continued until 2019. In 2020, the program was moved to the prime time slot of 9.30pm on Thursdays on the primary
ABC TV channel with a half-hour runtime. The new format brought in a rotation of presenters, with prominent Australians in the hosting chair for a series of episodes based around a theme. In 2020 journalist
Barrie Cassidy explored the idea of leadership, Paralympian
Kurt Fearnley spoke to people about excellence, and
Stan Grant did a series of interviews about identity. In 2021, the program moved to the primetime slot of 8pm Monday nights, with
drag queen and television personality
Courtney Act as host. Act's program was nominated for an
AACTA Award that year. In 2022 former Australian of the Year
Rosie Batty was added to roster of hosts on the show. ==See also==
