Decine di migliaia di manufatti, alcuni risalenti fino a cinquemila anni fa, sono stati scoperti dagli archeologi vicino a Newcastle, a nord di Sidney, grazie agli scavi in corso per la realizzazione di un'autostrada.
Negli otto anni finora dedicati a questa ricerca e lungo una distanza di 40 chilometri sono venuti alla luce 122 siti aborigeni, ognuno dei quali ha sfornato oggetti, parti di armi e utensili vari, per lo più in pietra.
Dalle analisi organiche è inoltre emerso che gli abitanti macellavano canguri e coltivavano diversi tipi di piante. Altre domande attendono ancora risposta.
