Actually this is line number 6 of all 707s built. Delivered originally to Pan Am as N712PA in 1958, it is pictured on taxiway 'Foxtrot' in front of a spring shower, having just arrived on the weekly service from Istanbul.
VH-ELT was withdrawn from use in 2013. Newcastle-Sydney air service is a legacy of its use by Aeropelican Air Services (July 1970-December 1975). Nationwide was -ELT's original owner and it was returned to it in 1976. The logo is Nationwide's.
