Not 100% sure, but it’s highly probable. I remember reading in the Year 11 Cambridge advanced math book something along the lines of “in NSW, it is typically learnt as All Stations To Central.”
I mean, it would not really make sense for it to originate in another country, as this is clearly a reference to central station (unless various other countries happen to have “central” stations, again not sure). My math teacher, who studied in India, learnt “All Silver Tea Cups.”
