A Victorian driver has been caught making a shopping list while she was driving.

The 46-year-old woman was spotted by police in the south-west Melbourne suburb of Williamstown this morning.

They observed that she was driving with her head down and not watching the road on a number of occasions.

The woman told police she had been writing a shopping list.

She was fined $388 and lost 3 demerit points for careless driving.

The national holiday road toll stands at six following the death of a man in Western Australia early on Monday.
