What is the earliest letter known to pass through the Port Moresby Post Office?
The eaeliest postmark has been reported as being on the 26th of August 1885. Before this some letters from Port Moresby had been endorsed with a Postmark “NG” enclosed in an oval of eight bars supplied by the Queensland Department of Posts and Telegraphs. Earlier letters probably had their stamps cancelled with a Cooktown postmarker. The stamps used in the early days and through to 1901 were those of the Colony of Queensland.
