Some of the same rules apply as in salt water, some are different:
Most fish like structure, whether to hide from predators or to hide from prey.
Agree with bigneil about marking fish and trolling that depth.
Worms on small hooks with floats can be very deadly.
If you're camping you may be able to put out traps for yabbies (check legality of course, I don't know for that area). Good for live bait or a feed.
There's no tidal flow so fish activity patterns are influenced by daylight, weather, water temperature.
Just like salt water, knowing what you're chasing and their specific habits is most of the battle.
For trolling, casting, or float fishing, contour lines can be very productive.
Spinnerbaits are good for fresh water, you can pick up the spinners by themselves and convert nearly any SP jig into a spinnerbait that's good for casting with a slow roll retrieve or for trolling. Control the depth of the lure with the weight of the jig head and speed of troll/retrieve. Spinnerbait are sensitive to trolling/retrieving too fast, so make sure you drop them alongside the boat to check how they run in the water and adjust accordingly. If it's too fast you'll see them leaning on an angle and they'll tend to skip up out of the water.
