Thousands of revellers swelter in heat at a music festival while across the country NSW is flooded

Perth revellers have sweltered in beautiful warm weather at a packed music festival while thousands of homes were damaged by floods in NSW.

The audience was bathed in sun in 34C heat at the SummerSalt Festival in Fremantle Park on Sunday in stark contrast to the other side of the country.

Western Australia has nothing but blue skies and temperatures from 24C to 31C for the next week while the rain in NSW won’t stop falling until Wednesday. 

Thousands of Perth residents were treated to hot summery weather over the weekend at the SummerSalt festival

Festival goers were required to bring a fold-up-chair to sit on but were able to dance in front of their seats in the sweltering heat. 

SummerSalt is a festival that travels around Australia taking shows to some of Australia’s most picturesque spots including Bella Vista Farm in Sydney and the Darwin Botanical Gardens.

The festival was headlined by Boy and Bear, The Cat Empire, John Butler, The Teskey Brothers, Montaigne and Emily Wurramara.

While Perth was enjoying the sun and heat, the NSW coast was subjected to the polar opposite with relentless rainfall. 

Sydney received over 110mm of rain over the weekend while Perth locals enjoyed the heat

110mm fell in the space of 24 hours over the weekend and it is not expected to stop as up to 60mm of rain is forecast to soak Sydney on Monday. 

Conditions were dangerous and volatile as flood warnings were issued for parts of western Sydney and the NSW mid-north coast on Sunday night.  

Rising floodwaters in Sydney’s west and north-west are now higher than the catastrophic 1961 flood, with residents of parts of Penrith told to leave their homes by 9pm before floods are expected to peak Sunday or early Monday.

Other residents in the area were told to get out by 4.30pm as the Nepean River burst its banks and torrents of water overwhelmed homes.

Many rivers burst their banks with widespread flooding occurring across the state

Late on Sunday evening the Bureau of Meteorology issued major flood warnings for the Hawkesbury, Nepean and Colo Rivers, warning of major flooding at Windsor, Sackville, Lower Portland and Wisemans Ferry.

The Hawkesbury at Richmond is forecast to reach 15metres by 7am Monday, with further rises possible. The river is expected to reach the same level at Windsor by 3pm.

Further evacuation warnings were issued for the western Sydney suburbs of Eastern Creek, Stonecutters Creek and Marsden Park, where residents were told to prepare to leave their homes by 3am.

A severe weather remains in place for much of the NSW coast all the way up to Queensland for life-threatening flash-flooding with 137 schools closed and workers urged to stay home on Monday.

There was numerous evacuation orders given to a number of different suburbs
