In 1931 the bank was granted a coat of arms from the College of Arms, symbolising the 1927 acquisition of the Western Australian Bank. The arms featured an emu and a black swan (which is symbolic of Western Australia) rampant supporting a shield surmounted by a kangaroo and the emblem of the rising sun. On the shield are shown a ship, two sheaves of wheat, a sheep, a cow, and a crossed pick and spade, representing the principal industries of Australia at the time: pastoral, agricultural, mining and shipping. The motto included was "Sic fortis Etruria crevit", translated as "Thus strong Etruria prospered", a line taken from Virgil's Second Georgic and an early motto of the Colony of New South Wales.
