John, the fire on a ceramic burner should be short blue flame.. not easy to find the ceramic here, but try Gas heating poeple and ask for the ceramic panels uesd on infra red heaters..
For your gas jet camping goods stores carry Primus jets. for lanterns and stoves using butane I fyou ask for a G jet or HM jet you will get the right thing..tap needed for the jet holder is 4.5mm by .5 mm pitch.. this may be hard in Brissy.. if so mail your jet holder to me and Ill do it..
