The cheapest option is the generic 1 or 2 inch rubber flare extension available from ebay. Personally I think they look like rubish but they get the job done and would be pretty easy to fit.

DBOR and Jeep Konnection have a decent range of flares. Most of them are direct swap overs you just remove the flare and liner screws undo the indicator connection and pull the flare out of its snaps and then snap the new one in and put the screws back in.

I think elephanaki is trying to sell some reasonable flares in SE Melbourne if you have a look in the for sale section.

Depending on the offset you may still be "in trouble" if you chance upon a knowledgable trafic cop but at least having them covered you won't draw the trouble.
