Australia used to have the "Easter bilby" in addition to the more common overseas Easter bunny. Sadly I think stores stopped selling chocolate Easter bilbies; I don't recall seeing any this year.
I think the Easter Billy thing may have been a fund raiser for the Save the Bilby Fund, though I’m not sure. Did some work with them in Charleville some time back, as part of a student field trip looking at design concepts for what eventually became the Bilby Experience. Great people.
From what I can remember they’ve had good success in rebuilding the bilby population.
