As bushfires scorch areas of NSW, one protester has started a fire of her own, setting her Centrelink debt letter alight.

At a rally outside Redfern's Centrelink in Sydney on Wednesday, Bec Hynek, 28, set her automated debt letter on fire as fellow protesters chanted 'burn the debt'.

Several dozen protesters tried to gain access to the Centrelink, banging on its locked doors before marching down Redfern Street.

However, as one Twitter user points one, the 28-year-old's dramatic display took place during a total fire ban

Protestors were met by a dozen uniformed officers, though no arrests were seen to be made.

'It [burning the letter] was a message and I wanted the message to be strong and make my voice heard,' the disability pensioner told Daily Mail Australia.

'I'm really frustrated – I get this Centrelink letter and I can't get through on the phone or on the website to resolve it.'

However, as one Twitter user points one, the 28-year-old's dramatic display took place during a total fire ban.

Areas in NSW - including Sydney - face a total fire ban, where lighting, maintaining or using a fire in the open is prohibited.

But Ms Hynek said there was no immediate danger.

'The fire was on concrete and there were no trees around, you can see it burns up straight away.'

She said she was much more concerned about her own health and those of thousands Australians wrongly accused of having unpaid welfare bills.

'It’s been a really difficult time for me and it's hard to be okay when I feel like this,' she told Daily Mail Australia.

Labor says a Senate inquiry is needed to see what can be done to fix the Centrelink debt recovery system.

Emergency warnings have been issued for two fast-moving fires burning east of Cessnock (pictured) in the NSW Hunter region

Total fire bans are declared during weather conditions when bush fires are more likely to spread and cause damage on days when the weather is very hot, dry and windy.

Sydney's west hit 44C on Tuesday afternoon and some regional parts of Adelaide pushed 44.7C while the world's best tennis players were subjected to 35C on court at the Australian Open in Melbourne.

Queenslanders fared slightly better with a maximum of 32C in the city, although the mercury is only expected to drop to the mid-20s overnight.

There will be some relief for most states later in the week, with temperatures dropping to 25C in Sydney on Thursday, 26C in Adelaide on Wednesday and 21C in Melbourne on Wednesday.

Brisbane has drawn the shortest stick, with maximum temperatures remaining above 30 for the rest of the week.

Experts have warned to expect similar conditions next week.
