Australian mushroom cook Erin Patterson appeared in court today facing two charges of attempted murder and three of murder.

A brief hearing was held at the Latrobe Valley magistrates court, with the case officially adjourned until May next year.

Her former in-laws Gail and Don Patterson as well as Gail's sister Heather died from suspected toxic mushroom poisoning in July, and Gail's husband Ian was hospitalised.

Melbourne journalist Nathan Currie joined Andrew Dickens.
