The Olivia Dean song at number one in Australia before “Rein Me In” replaced it was “Man I Need.”
Olivia Dean dominated the Australian chart during the song’s climb. “Man I Need” was already number one when “Rein Me In” reached number two on the ARIA Singles Chart in March 2026. In the chart week ending 3 April 2026, the Sam Fender and Olivia Dean collaboration moved to number one while “Man I Need” fell to number two.
That chart exchange was notable because it gave Dean consecutive control of the top position with two songs from her own catalogue and collaboration. It also marked “Rein Me In” as Sam Fender’s first Australian number-one hit and Dean’s second.
“Man I Need” should not be confused with Dean’s other listed Australian top-two hit, “So Easy (To Fall in Love),” which was at number two during the earlier stage of the song’s run. “Nice to Each Other” and “Lady Lady” are also Olivia Dean titles, but neither was the number-one track displaced by “Rein Me In.”
