On Thursday Jason Moyce, who runs the hugely-popular Facebook page Trapman Bermagui, handed out the free fish to anyone who came to the town's wharf on the afternoon, hoping to help people affected by the bushfires.

"I had a few people turn up who lost their homes," he said.

"That's all I need - one would have done, but that definitely made it worthwhile."

He said they came from the Cobargo region and one man who escaped as the fire burnt down his house only had "the shirt on his back".

It took Mr Moyce about 10 hours to fish for enough produce, but when he returned to shore it all disappeared quickly with about 100 people turning up and only one esky remaining after about an hour and a half.

He himself had made the last-minute decision to evacuate to Canberra after the fires hit the region as he wanted to make sure his five-year-old daughter was safe, although while waiting in the nation's capital for the chance to return he said he "felt a bit helpless".

When asked why he wanted to hold the seafood giveaway he said it was the least he could do.

"Everybody is really stressed out, there's not a lot of fresh food in town and I know locals love their seafood," Mr Moyce said.

He said he probably would not be able to return to the ocean over the next few days due to the predicted deteriorating conditions, but might consider running a similar giveaway next week.
