I found this
http://www.jbhifi.com.au/computers/toshiba/15-inch-notebook-sku-51606/
$943
Dual Core, AMD Turion(Don't know about the processor but it reminds me of turalyon and tirion mixed together which can be nothing but awesomeness)
4 GB Ram
Doesnt specify graphics card so I don't know usually that cant be a good thing
There's cheaper but they're all single core, the only exception being acer which i heard is terrible
