I think most Australian arty types have heard of Danie Mellor. A few people I know seem to hate him though, and I've never quite worked out why... the complaints given include: lack of skill (huh?), incomprehensibility, arty-fartiness yada yada.
Cynicism about art addressing Australia's horrific past is rare, and yet one of the few worthy artists working in that field seems to cop a lot of flack. Oh well.
