Should be lots of recreational traps out today in those areas. Better to set where other rec fishers are fishing, commercial guys often set in areas with more current. I’d study navionics boating app and look for large shelfs, where it gradually rises from 300-150 feet. Set at least two strings of two, with your traps set 30 feet apart. Set up hill at two different depths, so your traps will hopefully land at four different depths. make sure you are not close to any other rec traps as they may be setting parallel to shore. Record what depth on the sounder when each trap goes over. Check in an hour and if a trap has prawns in it reset in that spot and depth all your traps and soak for 2 hours. Good luck.
