This region covers the slopes and plains of northern NSW and southern Queensland, and the Queensland Central Tablelands that have summer-dominant rainfall, averaging 400 to 650 mm per year. Summers are hot and winters are moderately cold with more frosts in the eastern parts of NSW.
This region corresponds to the WestWorm (NSW DPI) and WormBuster 1 (except Stanthorpe), 2a and 2b (Qld DAFF) zones, plus the Central Tablelands of Qld.
These boundaries are approximations only as seasonal conditions vary.
