Rinehart has deep ties to agriculture that go back generations and that pastoral connection continues with S Kidman and Co, founded in 1899, and Hancock Agriculture, which breeds the world's best Full Blood Wagyu.

"Having grown up on stations, which I loved very much, stations and farms have and always will be close to my heart," Rinehart said.

"Rural Aid as an organisation that ‘stands with our mates in the bush' during their hard times, and it does get tough in the bush with floods, fires and severe drought in addition to the usual dangers of snakes, spiders and in some northern areas, crocodiles too.

"As patron of Rural Aid, I encourage all Australians to throw their support behind its ongoing efforts in ensuring that our food producers - our farmers- are able to get back on their feet quickly when drought, flood or bushfire hits them."

Rinehart said reserving the agricultural and mining industry's future is in the interests of not only all the businesses that the primary industries support, but every Australian.

"It is critical that our governments realise these essential industries must keep cost competitive internationally to be able to continue to earn export income and thrive, and not burden them with regulations and other onerous government burdens," Rinehart said.

Rural Aid Chief Executive Officer, John Warlters, said the charity is honoured to have Rinehart advocating the work they do in providing rapid assistance to farming families impacted by disasters. 

"We are appreciative of Mrs Rinehart's ongoing support and very much look forward to our valued friendship continuing into the future," Warlters said.
