OK, so it seems that the Australian tow hitch as fitted by the dealer is different from ones sold in other parts of the world

The two plastic bits I needed I will state the part numbers here for reference purposes in case someone else ever needs them - not sure which is the surround and which is the plug bit though
The parts fom Volvo Australia are VO9493899 and VO9493922 and were quoted at $33 in total for the pair

The reason I will never need these parts is because the crash repair shop decided to replace both the rear bumper and the towbar. With the spare wheel removed there was no sign of deformation of the floor or surrounding panels luckily so that seems to be the limit of the damage.

With the other driver admitting fault and my insurance cover including a free rental car from Hertz for the duration of the repair (probably some ghastly buzzy econo-box) things could have been much worse. It wont be until late January that the car will be repaired though.
