I bought that similar set up 8 years ago and its still going, beat it up, take it apart myself and rebuild the reel every year, as for the rod it is a great price for that rod.
I have pulled 30 lb white sea bass on that rod and reel set up then turn around and catch 1 lb sandies.
Have fun in the lagoon and not a bad idea to throw some fish traps or crocodiles in the river mouth for some halies.
