Formula One star Daniel Ricciardo has pledged his race suit from this year's Australian Grand Prix to help bushfire victims.

The 30-year-old racing driver, from Perth, made his generous promise in a video posted to social media on Saturday night, and urged others to donate as they can.

'Australia is suffering with some severe devastating bushfires,' he said.

'Anyone who is kind enough to donate, please do.

'There's the Australian Red Cross and there's WIRES wildlife rescue, I'm sure there's a bunch more but these are two I've donated to, so please - if you can.'

Ricciardo said to encourage people to donate, he would sign this year's Australian Grand Prix racing suit and raffle it off to raise funds to help those affected by Australia's catastrophic bushfires.

'I'll get some details further over the next few days,' he said.

'But my race suit I'll race with at this year's Australian Grand Prix - I'll sign that and we'll raffle that and all proceeds will go to those two charities as well.'

The Renault driver said his thoughts were with those who had suffered.

He joins other high-profile athletes who have joined the movement to help the victims of what may be Australia's worst ever bushfires.

American mixed martial artist Jorge Masvidal has offered to help by donating the proceeds of his February visit to Australia.

The welterweight champion also said on Twitter that he wants to physically help put out the fires when he is here.

Tennis talent Ash Barty announced at the Brisbane International on Sunday that she would donate $360,000 to families affected by bushfires if she wins at a major international competition.

'There have been really great initiatives from cricketers, tennis players, golfers, soccer players all over the country trying to help out,' she said.

'We have come to the decision any of my prize money here in Brisbane will be donated to the [Australian] Red Cross to go towards the families and homes affected.'

Australia's bushfires have burnt more than six million hectares of bushland and farmland across six states since October killing an estimated 25 people, 18 of whom were from New South Wales.

New South Wales and Victoria have been hardest hit with the fires destroying entire towns and killing more than a billion creatures including livestock and endangered wildlife species, with the survivors set to starve after their food sources and habitat were burnt.

More than 1,300 homes have been destroyed in New South Wales alone.

On Saturday Prime Minister Scott Morrison announced up to 3000 Australian Defence Force reserves would be called up to help the bushfire response effort for the first time in Australia's history.
