Well,this Aussie is awake - & I don't know either, we need Bob Bolton - where are you, Bob? Bob is my source of info - he knows almost everything (only once have I known some strange little fact he didn't!!)by-the-by - if the bushfire really is south of "Sidney", that's not my home town, so the G F A might be a typo, too. Much of Australia does contain red sand.
Let's wait for Bob - I'll send this to him in case he hasn't read it.

........ In Kieran's song "Roll you to the River" there is a reference to the G F A. The first verse is There is a bushfire south of Sidney a heatwave in old Queensland theres not much in the G F A but a pile of rusty sand.
