Freshwater tips

 Hi guys. 
im taking the family camping down at potters gorge, Wellington dam in a couple of weeks. I was hoping to take the kids fishing for some trout or Redfin, but don't really have any freshwater gear. Just wondering if I could get some recommendations on rod weight and line that would be appropriate? Also any tips on lures, or bait/hook size would be awesome! I've only ever really flyfished in freshwater, so this is new to me, but think would be a great way to get the kids enthused!

any advice greatly appreciated!

cheers!
