“Rein Me In” replaced Olivia Dean’s “Man I Need” at number one in Australia in April 2026. The two songs occupied the top two positions, with the duet moving to first and “Man I Need” falling to second.
The result created a notable self-replacement story for Dean. She was the performer on “Man I Need” and one of the two performers on “Rein Me In,” so her own release was displaced by a collaboration in which she also appeared. For Sam Fender, the change marked his first Australian number-one single.
The chart date can cause confusion because ARIA issue dates and reporting dates do not always fall on the same calendar day. The relevant chart week is dated 6 April 2026, while contemporary reports referred to the chart being published in early April. The other options were unrelated songs: “Manchild” and “Ordinary” were separate chart titles, while “Umbrella” was not the displaced number one.
