level towards the close of the mioceiie uprising (about pleistocene 

 times), producing tlie great block faulting in the south-eastern 

 knot." 



Quecnslanc] . — J. V. Danes (ref. 15, p. G, etc.), wlio chiefly 

 worked in Queensland areas, believes, in connnon witli Australian 

 "Workers whom he quotes, that the peneplain extended from New 

 Guinea to Tasmania and believes it '* to have been divided into 

 a large number of independent outletless basins witli shallow lakes." 

 (See also ref. 44.) 



South Australia. — Rev. W. Howchin (ref. 31), the chief autliority 

 on the physiographic features of South Australia, states regarding 

 the uplands of that State: "The old peneplain now stands at an 

 elevation of 1500 feet, with rivers flowing mostly in juvenile 

 gorges 300-500 feet deep." " The uplift probably coincided in 

 the main Avith the Kosciusko epocli of New South Wales physio- 

 graphers." (page 176). 



Tasmanin..—\\r. H. Twelvetrees (ref. 54, p. 162) states: "Since 

 Pleistocene times the north-west part of Tasmania has apparently 

 suffered an uplift relative to sea level, as evidenced by the exist- 

 ence of extensive elevated peneplains. Recent river systems have 

 deeply dissected the area, and seamed it with profound gorges." 

 L. Keitli Ward (ref. 54a, pp. 6-18), describes an interesting por- 

 tion of the dissected peneplain of north-western Tasmania. 



Western Australia. — J. T. Jutson (ref. 35 p. 95) discusses all the 

 available evidence, and concludes that the last great uplift of the 

 broad plateau of AVestern Australia was pre-pleistocene and post- 

 jurassic, probably early or late pliocene, while its reduction to a 

 peneplain had taken place probably in early or middle tertiary 

 times. 



Northern Territory. — W. (I. Woolnough (ref. 55, p. 45) states 

 that the " Most striking feature (of the Territory) is the extent 

 and uniformity of the plateau areas, 1000 feet or so above sea 

 level. . . . This vast upland is a peneplain of the most perfect 

 type and was formed by sub-aerial erosion at a time when the 

 country stood much lower than it does at present. ... It is 

 trenched by numerous rivers, wliich have reached base-level for a 

 long way up their valleys." 



Papua. — J. E. Came (ref. 11) does not deal specifically witli the 

 physiography, but mentions ^ " plateau deeply dissected by tor- 

 rential streams," and further states that this plateau " in part 

 consists of tertiary limestones of as late as pleistocene age."
