Hi Alan, nice radio. Looks like a hefty speaker for such a mid size radio. Nice that the dial has separate listings for your different Australian states. If you have some sort of lubricant/solvent like WD-40 that we have here, or electronic cleaner (if no electronics store, try an auto parts store) you can apply a couple of drops of it using a toothpick to the spring contact and bearings on the tuning capacitor, and then tune back and forth to work it in.

Also, the capacitor could be touching but you can't see it. If you have an ohmeter, turn it to the lowest ohm range, connect one lead to the capacitor frame, and the other to one of the stationary (stator) terminals and tune through the entire range with the set turned off. Your meter reading should not change throughout the range. The ohms number doesn't matter; just that it should not change. Try each of the other stator connections in turn. If any of them change around 800 and down, then there are plates touching. With the meter still connected try pushing a piece of card down each side of each plate on the offending section to see if you can find the short. The rotating (rotor) plate could then be bent back carefully.

It might be something else but this is where to start. Good luck!
