There are more questions than answers following the disappearance of a Victorian berry farmer during a bizarre family getaway.

The Tromp family left their Victorian home a week ago in a panic, after parents Mark and Jacoba feared for their lives.

Mark Tromp was found yesterday, dehydrated but otherwise healthy.

The couple's three children have admitted the events are "hard to explain."

Australian correspondent Murray Olds told Mike Hosking the events are nothing but weird.

"One daughter ends up in hospital, the mother then ends up in hospital two days later, the brother and sister end up back in Victoria while the old man's wondering around out in the bush somewhere.

Experts speculate the family were suffering from a kind of 'group schizophrenia'.

Meanwhile, an acknowledgement that mistakes do happen from New South Wales Health Minister Jillian Skinner, following the cremation of the wrong baby.

It resulted in a family bidding a tough farewell to the wrong child.

There are now multiple calls for the minister to resign.

Murray Olds said this follows a string of tragic errors by hospital staff.

"This comes after the death of one baby and the brain damage suffered by a second brand new baby. They were given nitrous oxide instead of oxygen in the birthing theatre."

Birthing units aren't the only ones under fire, given earlier this month it emerged more than 130 cancer patients received incorrect chemotherapy doses at New South Wales hospitals.
