Most suppliers here in Australia make their catalogues available in May (late Autumn), with delivery into winter. I expect the orders from Van Diemen Quality Bulbs and Tesselaar to turn up in the next couple of weeks. No idea on the timeline for Golden Ray Gardens, though. Also I've noted a few places have the Asiatics ready to ship but not Orientals, with one stating that they won't be available until July. I suspect it might have had to do with the weather this year (being warm up till mid May) and the fact that the coldest period is typically around August.
