There is fly fishing in most parts of the country. You will have to decide whether you want to fish on rivers or on still water. You can kit yourself out quite cheaply with a flyfishing kit, you don't need expensive gear and don't be fooled by the salesman. My 5 year old son caught his first trout on a �10 rod this year.
If you want to fish on the river for trout, you only have 2 weeks of the season left.
A good place to visit or contact by phone would be John norris of penrith, they are the biggest fishing shop in the area.
