On 27 Jun I ordered a marriage certificate from GRO - despatch date given as 3 July
It reached the Brisbane, Queensland mail exchange 7 July and was in my mailbox by 9am 8th July. The print date is July 1, so it may have been posted before the 3rd - unfortunately there is no postal date on the envelope.
I am so impressed - Took my folks 7 months to get to Australia in 1833

To get a certificate from the Qld BDM registry - about 20 km from where I live takes 8 weeks. I am going to send the registrar a scan of these details

Edit: If you have any ideas as to the name of the Vicar - much appreciated
