Search continues for missing Vic women

A three-day search for an elderly woman and her disabled daughter has failed to track down the pair in regional Victoria.

Elizabeth Stephens, 89, and her daughter Judy Stephens, 53, were last seen on Sunday afternoon ordering a small meal at Tatong Tavern in Benalla.

Senior Sergeant Mark Byers told AAP on Thursday there was "increasing concern" for the women due to Mrs Stephens' age and her daughter's intellectual disability and insulin dependency.

The tavern's owner Christopher McCabe said women were "visiting a relative for dinner that evening" and neither seemed distressed.

But the search only began on Tuesday after the pair were reported missing about noon that day.

Snr Sgt Byers said the search has expanded from Tatong Tavern to Benalla and surrounds to Winton Wetlands, which included significant bushland and farmland.

The women are believed to be travelling in a 2007 Toyota Yaris with the registration number WAB580.
