Heavy Duty trailer net repairs, Melbourne

Good afternoon, I know it is a long shot, but I need to get a heavy duty trailer net repaired. It was originally made by a guy in Dandenong Vic and is made the same as a fishing net. I borrowed my mates trailer and he said that the nets goes with it, long story, I damaged it and it needs to be repaired or replaced. Does anybody know of anybody that may be able to help, preferably in Melbourne, but anywhere will do. I have done a Google search for net makers and the only one that got back to me couldn't help. TIA.
