JACQUI Steele has hundreds of animals at the Big Ears Animal Sanctuary - many sick and traumatised.
They cost her roughly $1500 a week, mostly covered by donations, while her husband Brett - a police officer - covers the rest.
It's a seven-day-a-week operation, and Mrs Steele relies heavily on volunteers to keep things moving while she fights a terminal illness.
Mrs Steele said her advanced breast cancer was one of many uncertainties that surrounded the daily operation of Big Ears.
But the 42-year-old didn't fear for the future of the farm.
"I worry about what will happen to Brett, and I worry about the animals," she said.
"But this thing is bigger than me.
"The cancer is terminal, but it is my heartfelt intention, and the intention of the board, to keep going if I die.
"It might be that we stop taking on animals for a while until we transition, but things will certainly go on without me."
Mr and Mrs Steele founded their non-profit organisation in 2004 after witnessing mistreatment of donkeys during a trip to Egypt.
Their 12-hectare property near Longford now houses 400 domestic and farm animals, including 200 rabbits and guinea pigs, an assortment of poultry, donkeys, goats, pigs, ponies, cows, sheep, and - for good measure - two emus.
"We were initially looking at farm animals, because they tend to miss out a bit," Mrs Steele said.
"A number of other agencies already deal with domestic animals, like cats and dogs, including the RSPCA and Dogs Home of Tasmania.
"But no one really wants to adopt the larger animals."
Mrs Steele said the farm operated off a $80,000 annual budget - which included a $20,000 vet bill.
No wages are paid at Big Ears, and work is carried out by a group of 10 volunteers.
About 75 per cent of the total costs are covered by donations, including the popular sponsor program that allows people to "own" a specific animal for 12 months.
The rest comes out of Mr Steele's wage as a police prosecutor.
"We never have a large amount sitting in the bank," Mr Steele said.
"So we only know for sure if we can keep going one year into the future.
"Ideally we'd like to get to the point where we have a trust set up that will guarantee the farm will run for another five years."
Mrs Steele said her health and the farm's finances meant there was always a degree of uncertainty at Big Ears.
"I don't know how long I've got left, which is frustrating," she said.
"I'm actually not supposed to be here now.
"But the doctor says whatever I'm doing keep going with it, because it is working."
