The man and his wife, who wished to remain anonymous, donated $10,000 to The Examiner's Winter Relief Appeal, $5000 to disability sport and recreation organisation New Horizons and intend to donate the next $5000 - due in October - to Crohn's disease research organisation Propel A Cure.

He said the coronavirus pandemic had not affected him, so it made sense to provide the extra funds to benefit the community.

"We weren't greatly affected by the pandemic so we thought rather than keep the funds ourselves, we'd try and help charity with it, as they have extra needs with the pandemic," he said.

"All Tasmanians know about The Examiner Appeal, and my wife has friends with children that benefit from New Horizons."

The funding came from automatic payments, starting in April, made to businesses with a turnover under $50 million. The minimum amount for businesses with one employee - such as the man from Trevallyn - started at $10,000, $5000 and another $5000, which flowed with the lodging of quarterly business activity statements.

Businesses did not need to apply for the cash flow boost.

Not-for-profit organisations who employ people were also provided with the payments.

The retired accountant's donation was the latest good news for New Horizons, which has received strong support from the community in recent months.

Last month, Launceston 11-year-old Harry Tucker raised $1000 for the organisation through a reverse raffle at his school, while they also benefited from a $5000 grant from Hydro Tasmania. The Fit 'n' Kicking 2020 Mount Barrow Challenge, scheduled for October 25, will raise funds for New Horizons.

The donations have been crucial in allowing New Horizons to bring back the majority of its programs once social distancing restrictions were lifted in Tasmania.

The organisation's application for funding under the National Disability Insurance Scheme's Information, Linkages and Capacity grants was unsuccessful in February, forcing New Horizons to reevaluate its programs with fears it could run out of funding.

New Horizons planned to carry out fundraising events, but the coronavirus pandemic forced another rethink.

Chief executive officer Edwina Dick said they were reluctant to rattle the tin at a time when so many were struggling, so the unprompted donations from individuals had been wonderful.

"It's not just a cash boost, but it's a psychological boost for us as well. It shows us how valuable New Horizons is to the community, and that people are thinking of us and pitching in to help," she said.

"With COVID, suddenly it wasn't just New Horizons that was in trouble, it was everyone - all organisations, local businesses big and small.

"We had to cancel our bike ride and gala due to social distancing, but we were conscious of the fact that the local community has supported us so well over 30 years, so we didn't want to be asking of businesses, but instead we wanted to be able to give back."

Ms Dick said they were hopeful of another round of NDIS funding in the near future.

"We were so close to getting the funding last time. The issue wasn't with our application or our programs, there just wasn't enough funding to go round," she said.

"They saw that there were so many other worthwhile projects and organisations that required funding, so hopefully the grants open up again."

New Horizons has been able to bring back about three-quarters of its programs, including swimming, taekwondo, gym, futsal, craft, woodwork rebound therapy and its programs in Hobart and Scottsdale.
