Thanks again to all who took the time to contribute.

We have snaffled a PO Box in a nearby suburb. I will post there, at least initially, preparing as much as possible at home first. Reasonably close parking looks possible, and it is moderately accessable by public transport, should my need ever arrive. One of the counter staff is an old friend  for used to work at our branch, and we have met the Manager. 

I will leave the Red Box for emergencies only. Now to get started on changing  XXXX  mailing addresses.
