The paddlers have returned to the Border for a short break as they wait for stable conditions to finish the last two legs (about 100 kilometres) to the Tasmania mainland.

Stuart, who has described the weather conditions as "not too flash", said safety concerns about the notorious stretch of ocean had led to the decision to return to Albury "to our respective jobs" and wait for relatively smooth sailing to complete their quest to raise awareness and funds for suicide prevention and mental health.

"We have been unable to paddle today, tomorrow and really for at least another 10 days," he said on Wednesday.

"We have decided to press pause on the last two legs of the crossing for a few weeks.

"Thank you for all your support and assistance and both Matt and I are comfortable that the decision to pause the crossing is the most responsible and safe option."

Matt will return home to his wife and young child nursing a "crook wrist" while Stuart is battling some brutal blisters on his right hand.

However the long-time mates are absolutely committed to finishing their adventure - the sea kayak, paddling gear, tent and food has been stored at local builder Guy Ireland's place, about three kilometres from Trousers Point Beach.

Stuart said the pair had been overwhelmed by the support of the Flinders Island community (population of about 900 residents) with locals Tom and Jo Youl putting them up in their home for several days.

"This cause brings people together and the level of support for what we are doing is just incredible - we are very grateful," he said.

Stuart said there was a window of just 36 hours to complete their Paddle for Survivors mission, which is raising funds for this year's Albury-Wodonga Winter Solstice and advocacy group Australians for Mental Health.
