Many commented asking about Bob, with one Facebook user writing: “What about great grandpa sick of the Irwins.”
Another wrote: “What about BOB??? Ask ya Mum.”
Now, Bob has been estranged from the family since his departure from Australia Zoo, shortly after Steve’s death.
He revealed in an interview for Australian Story in 2008: “I just felt that it was better for everybody concerned if I left Australia Zoo and Judy and I and all our friends were able to continue Steve’s work the way I believe it should be done.”
