Just go to Australia Zoo.
I cannot stress enough how amazing this place is. The difference to other zoos and petting zoos... I feel like its wrong to even put Australia Zoo in the same category as them. They are a sanctuary. A haven.
Forget the little patch of dirt and the animals stressed out and hiding in the corner to avoid being touched. The animals have space and freedom roam. They look happy to be there.
I really like how they don't outright ask for donations (though I would assume that would be appreciated to help continue their work) instead they ask for everyone to plant a native plant in their garden, to make a space for local wildlife. It is refreshing and nice to be personally involved at a "grassroots" level.
All I can say is thank you Australia Zoo.
