This beauty is a Common Garden Orb Web Spider (Argiope Australis) which has caught a beetle in its web. It is a large spider and I took three different views to do justice to this spider. The thick zig-zag line in the web is a trademark of Orb Web spiders. This particular spider is quite pale colored, it may have moulted recently and was sitting face-down in its web as depicted.
