The GoFundMe campaign is now aiming for $10,000, to support a woman who has given an incalculable amount to the community.

Trish Goss lives on the island with her husband and two young sons, named Flinders and Tasman.

She requires at least seven weeks of radiation therapy in Launceston, and has decided it is more economical to stay in the city, rather than repeatedly fly to and from Flinders.

Sammi Gowthorp, who organised the fundraiser, said the money would enable Trish's family to visit her and be with her while she faces her battle with cancer.

"Trish is very deserving of this; she is a well-loved member of the community," she said.

"She's getting on the plane to go to Launceston, and she's still running around doing things for people - dropping off things.

"The community is like that here though. Community is everything, when you live on an isolated island."

Ms Gowthorp particularly highlighted Trish's drive to secure $75,000 for a new playground.

The thousands of dollars raised for Trish Goss come from $50 to $100 donations from dozens of Flinders Island residents.

The nurse noticed many former patients among those donating to help her in her own time of need.

"She said 'there's so many people there that I can think of something I've done for them'," Ms Gowthorp said.

"She's such a giver, she gives so much and now with this the community can give back to her - I've said to her, take it as a gift.
