If I was you Mal I would go to the local Market, find the tool stall and ask the guy for a tap wrench, get him to show you how it works and then ask him if he has any tap connector washers, half inch for sink and basin, three quarters for a bath, if you cant get them there go to a local diy place, whilst your there ask for a small tub of 'plumbers mait' then go home turn off the water and undo the tap to let the pressure out, then get under there and remove the tap connector followed by the big nut, if you cant undo it all the way dont worry, as long as you have enough room to put a ring of plumbers mait under it between the tap and the body the jobs nearly done, screw it back together as tight as you can so that plumbers mait squezes out from underneath the tap, then put a new washer into the connector to the tap, this can sometimes be awkward to get out, but does really need doing.
screw it back together and its as good as new.
