Hamilton’s Instagram post included a video of a koala being saved from the devastating fires by volunteers and he also included a string of links to wildlife and fire services pages that fans can support.
Hamilton’s post came after he had highlighted on his Instagram story how agricultural practices in Australia have contributed to global warming and he had encouraged fans to go vegan.
Hamilton is due to begin his World Drivers’ Championship title defence at the Australian Grand Prix in Melbourne in March.
The bushfires have put the race under threat, though, with F1 chiefs consulting organisers on a day-to-day basis to determine the best cause of action.
Air-quality in the state of Victoria has plunged to dangerous levels and the Australian Grand Prix might have to be postponed.
