VH-ESH was the very first HEMS / SAR AW139 introduced to Australia in 2007, and thus the oldest when pictured in Archerfield in September 2022, operating under callsign "RSCU500". Since 2007, some 35 additional AW139 followed with different australian HEMS / SAR operators, the Queensland Government Air (Service) being one of them, operating five AW139's.
