Oil drain back kit

Howdy folks. I'm in need of the oil drain back kit. Does anyone know of a stockist in West Australia or will I have to order the kit from Zip-ty in the states? Secondly, how in gods name do you get the old drain plug out when the previous owner has completely rounded the nut? I cant budge the nut at all. Will the engine have to be removed to access that #*%#@& nut? Any help would be awesome. thanks.

If you search forums, you will find detailed solution to this not uncommon drain plug problem. From memory, solution includes heat, cold (aerosol coolant?), hammer, chisel.
