In Australia, three people are dead and a fourth is in a critical condition after eating a meal containing toxic wild mushrooms.

Victorian Police have questioned and released one person without charge.

Australian correspondent Oliver Peterson says it's a small community in Leongatha, South Gippsland.

"This is an awful set of circumstances. Could you just think- having that family gathering and having a meal with some friends, you'd be going home at the end of the day. What was in these mushrooms, where did they get these mushrooms?"
