According to the search results, Qantas retired its last Boeing 747 in July 2020. The retirement came six months early due to the impact of the pandemic on air travel. The final passenger flight operated by the aircraft was from Johannesburg to Sydney as QF64 on January 13th, 2015. After retirement, the planes were sent to boneyards in California, where they were either stored or scrapped. The final Qantas Boeing 747 that flew out of the Mojave boneyard in June 2022 will likely never take to the skies again, as it was purchased by new owners Kalitta Air for parts.
