Wireless Weekly was Australia's first news-stand wireless magazine (not counting the "AWA monthly"), published in 1922 in Sydney by W.J. Maclardy, a founder of commercial radio station 2SB (later changed to 2BL).
 It arose from conversations between Florence Violet (Vera) McKenzie OBE (née Wallace), aka 'Violet Wallace, 'Vera Wallace' and later 'Mrs Mac' (1890-1982), who owned a wireless shop in the Royal Arcade, Sydney, Ron Marsden her engineer, and Maclardy.
