Three months later I have still to receive the courtesy of a reply. Seems they've yet to get their act together. On a Sunday close to St Andrew's Day this ceremony is practised in at least Sydney and Brisbane. Organised by the local Clans Congress it involves clan leaders marching into some presbyterian or uniting church in strict order of precedence. They are led in by someone carrying a saltire flag alongside another with the Australian flag.
Clan tartans are worn and so-called clan banners are carried in the procession.
Highlight of the ceremony is when wee bits of tartan are brought out and prayed over or blessed. I've no objection. What concerns me is the mythos developed around the rite. It all started, so the story goes, when the tartan was banned after the fall of Bonnie Prince Charlie. To cherish its memory parishioners took wee bits of the stuff to kirk every sabbath to have it blessed, the ceremony has persisted up until today.
