Australia's east coast will continue to get an early taste of summer with warm weather and sunny skies, while Perth will be hit with a chilly blast.
A slow-moving low pressure trough is gradually pushing eastwards and bringing warm winds into the east coast with Sydney and Brisbane experiencing high temperatures for the entirety of the long weekend.
Sydney is expected to hit 27C on Sunday and 29C on Monday, with residents keen to make the most of their three-day weekend.

Northerly winds are responsible for Sunday's 5C-above-average day with a high of 27C as Sydneysiders are expected to flock east to the city's beaches.
Winds will turn northeasterly along the coast which will bring cooler afternoon temperatures, Weatherzone's Felix Levesque said.
'Further to the west and away from this seabreeze, the mercury will continue to climb, peaking at 33C and 32C degrees for Penrith and Blacktown respectively,' he said.
'The final day of the long weekend will be the warmest with temperatures reaching 29C in Sydney and 33C in Blacktown and Penrith, about seven degrees above average.'
A drop in temperature will hit the city after the sun sets on Monday with a cool southerly wind reaching the city.
The cooling event in addition to a low-pressure trough will lead to a string of chilly days and rain for the remainder of the week.
Waverley Council, which includes Bondi, Coogee, and Tamarama beaches, released a warning for prospective beachgoers.
