Agency chief Ricardo Galvao said his mandate was terminated early due to an “unsustainable situation” following a meeting with Brazil’s Minister of Science.

The RSPCA is releasing images and reports of the worst animal cruelty cases in South Australia in a bid to highlight the extent of neglect in the state.
