Australia bushfires: Bindi Irwin opens up about missing father Steve in emotional Instagram post

Bindi Irwin has shared a heart-wrenching Instagram post amid the devastating Australia bushfires.

On Tuesday the 21-year-old shared a picture of her late father Steve Irwin.

"Dad spent his life working so hard to protect wildlife and wild places, especially in Australia," she wrote.

"I wish he was here right now to give advice and strength during this time of devastation with the bush fires. I know that his spirit lives on through our conservation work and I hope together we can make him proud."

Steve Irwin died in September 2006 after being stung in the chest by a stingray while filming near Port Douglas in Queensland. The wildlife expert was 44-years-old at the time of his death. 

The Iriwin family has been working tirelessly to save animals injured in the catastrophic fires.

Bindi previously posted to say the Australia Zoo's wildlife hospital is busier than ever.

"[We have] officially treated over 90,000 patients," she wrote. 

Her brother, Robert Irwin also made a post on Instagram to thank firefighters and other volunteers stepping up amid the crisis.

"Proud to be one of the many who are coming together to try and affect some positive change during this incredibly difficult time," he wrote.

"We're here to help where we can for wildlife and to treat the survivors."

It's estimated more than half a billion wildlife across Australia have been killed in the catastrophic fires which have decimated more than 10 million hectares.
