Sydney and its surrounds have shivered through its coldest June morning in five years as Australia’s cold change hits new extremes.

Early recordings from the Bureau of Meteorology have minimum temperatures across most of Sydney, except for the Airport, Observatory Hill and Harbour dropping below 5C on Wednesday morning.

Richmond, in the northwest of Greater Sydney, plummeted to -6.2C in the early hours of Wednesday morning.

Meanwhile Camden and Campbelltown, in the southwest, fared only marginally better, with minimums dropping to -2.3 and -1.6 degrees, respectively, before 7am on Wednesday.
