The occurrence of whistling atmospherics at four Australian stations (Brisbane, Adelaide, Hobart, and Macquarie Island) over the LG.Y. period is discussed. A strong seasonal variation is observed at each station, with the maximum occurrenceduring local winter, and also a strong diurnal variation with a minimum during daylight hours. Whistlers are observed more commonly at about geomagnetic latitude 45�. Autocorrelation analysis suggests recurrence tendencies in the occurrence figures and cross�correlation with sunspot numbers and Adelaide data indicates an association between the two. There is little evidence of association between whistler occurrence .and magnetic planetary index.
