A keen angler, Mr Dinneen loved fishing and wanted other people to have the experience.
"Competitors can fish from anywhere. Whether it is from a boat, the wharf, the rocks or the beach, as long as it was caught during the competition it will be eligible for the weigh-in, he said.
Mr Dinneen was still looking for sponsorship.
"We have received good support from local businesses, but would love to hear from anyone else who can help us or is willing to donate items suitable as spot prizes," he said.
Along with great prizes, there would be a charity and bait auctions, raffles and spot prizes. Mr Dinneen said the competition starts with a briefing at 7pm on February 26, fishing starts at 9pm, with the weigh-in the next day between 4pm and 6pm and prizegiving from 7.30pm.
All funds raised will go the Wish 4 Fish Charitable Trust, he said.
The trust leased a boat to take people out fishing but the long-term goal was to build a 13-metre powered catamaran under an initiative called Project Noah, to be launched later this year.
The entry fee is $45 per adult, $150 per team of four anglers, and $15 per child.
