The Tasmania Project, led by the Institute for Social Change at UTAS, surveyed more than 1,170 Tasmanians from across the state about food access and supply during the pandemic and associated lockdown.

The results showed food shortages had more than doubled.

"Previous studies have found that between six per cent and 11 per cent of Tasmanians are food-insecure, and our survey results far exceed these statistics," research fellow Dr Katherine Kent said.

The survey showed that the most vulnerable groups were young Tasmanians (18-24 years), single-parent households, those with a disability, Aboriginal and/or Torres Strait Islanders and temporary residents.

These groups experienced levels of food insecurity between 31 and 59 per cent.

Dr Kent said a coordinated, collaborative approach between key organisations was necessary to ensure all Tasmanians had enough to eat, regardless of where they live or how much money they have.

The Examiner is raising money for four charities that provide food relief and other supports: the Benevolent Society, St Vincent de Paul, The Salvation Army and City Mission, through the Winter Relief appeal.

More than $28,000 has been raised, with a goal of $70,000 to help struggling Tasmanians.
