Palaeomagnetic results have been obtained from four Australian igneous rock formations ranging in age from Early Jurassic to Early Cretaceous. These new sampling localities cover a much larger area than previously represented by Australian data. It is demonstrated that the pole positions yielded by the Kangaroo Island basalt (viz. 39° S 183° E, A95 = 11°) dated at 170 m.y. and the Early Jurassic western Victoria basalts (viz. 47° S 18 6° E, A 95 = 4°) agree with results from other continents in the context of Gondwanaland. The pole position for the Bendigo dykes (47° S 135° E, A95 = 39°) confirm the 'anomalous' results previously obtained from southeastern Australia. The fourth pole position, obtained from the Bunbury basalt of Western Australia (dated at around 90 m.y.) is in good agreement with other Cretaceous data for Australia, implying that pole positions for the Jurrassic and Cretaceous periods should now be considered separately.
