Also during his incumbency, Scarce presented the deed of title at the Maralinga Tjarutja Section 400 Handback Ceremony at the Maralinga Village. Section 400 was a 3,126 km2 parcel of land, located from the Oak Valley Aboriginal Community. The ceremony marked the return of Section 400 to its traditional owners, which had previously been disallowed access due to radioactive contamination. The contamination was a legacy of a program of British nuclear weapons tests which ran from 1956 until 1963. Seven major nuclear weapons tests occurred in 1956 and 1957 followed by a series of 'minor' tests which included the explosive scattering of of plutonium.
