I grew up there and its a great place for paddling. Its been dry for the last few years, but there are creeks, lots of good ww rivers are dam controlled (pros and cons) there's fantastic coast line for sea kayaking, surf spots......
Small but active paddling scene. check out
www.cataractgorge.com for a great event that drags out all the locals plus the best boaters from 'the mainland' and NZ.
Other outdoor acitivities are good too; biking, climbing, - take your pick if the rivers are too dry!
