Sharon Thomas believes that although many people in regional communities are interested in looking after injured animals, they can often do the creatures more harm because they don't know how to treat them.

Native animals require specialised diets, often free of lactose, meaning regular cows' milk could make them sick. Injuries that are not checked by vets may also heal incorrectly or become infected.

"There's lots of farmers and a lot of people who take on wildlife without knowing it's illegal if you aren't licenced," Ms Thomas said.

Becoming a licenced wildlife rehabilitator or animal foster carer is free. Training and mentoring is organised by the DSE.

For at least 10 years Ms Thomas, who works as an on-call nurse, has treated lizards, possums, joeys, native birds and echidnas.

She encouraged anyone passionate about caring for animals to become a foster carer, but said it was important people did not consider the wildlife as pets.

"We rehabilitate to get them back to flying or walking, then I give the DSE a ring and they find an appropriate place to release them," Ms Thomas said.

"During the night I get up and feed them and toilet them. Sometimes it feels like looking after your own baby but it is rewarding to know that they've survived."

Volunteers at animal shelters were given a boost this week with a State Government announcement that grants of up to $5000 are available through the Wildlife Rehabilitator Grants Program.

A total of $1.2 million will be spent across the state on the program in the next four years.

"Without these wildlife shelter operators and wildlife foster carers some of our beloved native wildlife would be left without much-needed support," Minister for Environment and Climate Change Ryan Smith said.
