Led by current Australian Amateur Champion Stacey Keating, the Victorians were too strong, defeating Tasmania 6 matches to 2.
Queensland is just half a match behind Victoria after their 5Ã‚Â½ to 2Ã‚Â½ defeat of South Australia, while Western Australia squeezed past defending champions, New South Wales 4Ã‚Â½ to 3Ã‚Â½.
It was always going to be a tough assignment for the New South Wales team after they were down 2Ã‚Â½ matches to a Ã‚Â½ after the morning's foursomes event.
The Gladys Hay Memorial Cup also saw the welcome return from a wrist injury for Western Australia's national squad member Whitney Hillier. The 19-year-old won both her matches, a 7 and 6 defeat of Adriana Brent in the afternoon singles match particularly impressive.
If NSW is to keep its hopes of winning a third consecutive title alive, they must defeat Victoria tomorrow while in the other matches, Western Australia takes on South Australia and Queensland meets Tasmania.
