Since late 2016, Westpac Rescue operates four AW139 helicopters from three bases, which are located at the airports of Belmont, Tamworth and Lismore. Covering the northeastern corner of New South Wales, three AW139 are on a 24/7 stand-by, while the 4th is either in maintenance or serves as a back-up. VH-ZXA pictured here was the first delivered in May 2016, followed by VH-ZXB (c/n 31733), VH-ZXC (c/n 31737) and finally VH-ZXD (c/n 31738). The yellow / red c/s stem from the beginnings with "Surf Lifesaving", while the white c/s represents the partnership with NSW Ambulance and NSW Health.
