In 2024 Olsen Gallery began 63 Jersey Art Sales, in partnership with Brett Ballard Art. Brett is the former Head of Art at Menzies Art Brands, Sydney and an extended period as Senior Specialist, Art with Sotheby’s Australia (now Smith & Singer). Named for the Olsen Gallery’s Woollahra address, 63 Jersey adds to the gallery’s business model, with pre-owned works by eminent artists such as Nicholas Harding, Emily Kngwarreye, Fiona Lowry, Tim Maguire, William Delafield Cook, Margaret Olley, John Olsen and other luminaries now sharing space with the newer names.
