The loved one of a missing fisherman has revealed rescuers are in a race against time to find him as looming bad weather threatens to halt their search efforts.

Mohammed “Micky” Hamade, 35, set off from Dolans Bay, in Sydney’s south, in his six-metre boat about 9am on Tuesday, but failed to return home that night to his wife and three children.

Authorities later found his boat idling about 30km off Port Kembla about 12.15am on Wednesday, but there was no sign of Hamade.

As a major search operation — which has involved not only authorities but scores of Hamade’s loved ones— reached its fifth day on Sunday, Mohammed Saad shared a video to Facebook revealing the timeframe to find him is narrowing.

“It’s the last good day for the next week to get out there,” he said, his eyes brimming with tears.

“We are currently on the way to Ulladulla. Thank you for everyone’s help. Inshallah (god willing) we can find him and locate him today.

“As I said, the weather does worsen from tomorrow for the next week, with big wind and big rain.

“So today will most likely be the last day that we can head out.”

Saad shared his gratitude for everyone who has assisted in the search to find Hamade, which has included a group of 40 volunteers.

“Thank you, thank you. Honestly, thank you,” he said.

“Not just from me, from his family, for everyone who has headed out.

“I wish I could show everyone the amount of messages I get about where to look and where to go and how to help.

“Micky deserved that. He deserved it more than anyone.”

Hamade’s family have offered a $25,000 reward for anyone who can help bring him home.

Volunteers have spent the past few days travelling between Sydney and the NSW south coast to conduct searches in tough weather conditions.

Friend Mick Kaz said he and 39 other men have been split into groups of four or five to pore over beaches, harbours, and headlands from Sussex Inlet down to Bateman’s Bay.

“We have been out all night having a look through out the beaches, the headlands, the rocks, the cliffs — anything that could give us a chance,” he said on Sunday morning.

“We have tried to look for signs — and the main sign we looked for was seeing the currents push the seaweed and debris onto shore.

“Lord give us a miracle today. Bless us and give us a sign to try and locate our brother Mohammed.”

The update comes as Hamade’s friends have rallied to support his family, with a GoFundMe set up to assist them financially with bills and unforeseen costs as they navigate the crisis.

Organiser Kassem Bazzi said Hamade “was a devoted husband to his wife and a loving father to their three beautiful children” who was “loved by many with his selfless nature, charming smile and laugh that lightened any mood”.

“His disappearance has brought darkness to whomever knows him. Leaving his family in unimaginable pain, facing uncertainty while trying to hold on to hope that has now diminished,” Bazzi said.

“Micky’s friends are banding. Raising funds to help his wife and children with not only everyday expenses, bills, and any unforeseen costs as they navigate this crisis but to be able to establish a foundation that Micky is no longer around for.”

Authorities involved in the search include Water Police, Marine Rescue NSW and Surf Life Saving, and the Joint Rescue Coordination Centre, which has been managing several aircrafts.
