This paper reports new geomorphological mapping, and reviews the extent, dating, pattern, and nature of past glaciation of the Tasmania's Central Plateau. The Last Glacial Maximum (LGM) ice limits on the southern part of the Central Plateau

This paper examines the application of amino acid racemisation (AAR) and electron spin resonance (ESR) to dating coastal sediments in Tasmania. The principal study areas selected are the Hobart region and the northwest coast near Smithton, where
richly fossiliferous Pleistocene coastal sediments provide the least ambiguous evidence for neotectonic uplift processes in Tasmania.

Observational studies on Cainozoic environmental changes in both Tasmania and East Antarctica have led to important modifications in the accepted interpretation of the history of glaciation for each area. A crucial role has been played
by the integration of the methods of glacial geomorphology, stratigraphy, sedimentology and dating methods. From studies based on combinations of these approaches, a model of multiple glaciations has been developed to explain observed features in Tasmania. This model

Lake Johnston cirque contains some of the best subalpine rainforest in Tasmania. The vegetation composition was studied to determine locally sourced pollen inputs and to interpret the pollen diagram. Magnetic measurements of mineral properties

This paper explores processes of bank erosion and sediment generation in Ripple Creek canal, Tasmania. Bank erosion within the canal is significant and is perceived to be adversely affecting water quality and fish habitat in the lake. In terms
Examination of colluvium mantles and associated alluvial fans along a low altitude transect extending 65 km through western and south-western Tasmania indicates there to have been negligible development of these features inside the ice limits

The Stanley River in western Tasmania, Australia, contains sub-fossil rainforest logs within the channel and floodplain. Of the more than 85 radiocarbon dates obtained, all but 3 date from 17 ka to the present and permit an interpretation of fluvial
Littoral habitats in large rivers are influenced to varying degrees by changes in discharge. This study has highlighted the differences in macroinvertebrate assemblages of several littoral habitats in two lowland rivers in Tasmania. Differences
