From comments left on my previous entry about having mail dealt with, I've looked into a few other offerings of this service. We would prefer a service where you can pay as you go rather than having to pay a membership fee. Most Australians would have their mail back home dealt with by a family member or friend. For us, thhere would only be a handful of items within the UK.
Other than UKPostBox there was another suggestion called Boatmail that also offers the service on a pay as you go basis.
Here are the links to their fee pages :
