We report here on extragalactic large-scale structures uncovered by a deep optical survey for galaxies behind the southern Milky Way. Systematic visual inspection of the ESO/SRC-survey revealed over 10000 previously unknown galaxies in the region tex2html_wrap_inline468. With subsequently obtained redshifts of more than 10% of these galaxies, new structures across the Milky Way are unveiled, such as a filament at tex2html_wrap_inline470 km tex2html_wrap_inline472\ connecting to the Hydra and Antlia clusters, a shallow extended supercluster in Vela (tex2html_wrap_inline474 km tex2html_wrap_inline472), and a nearby (4882 km tex2html_wrap_inline472), very massive (tex2html_wrap_inline480), rich Coma-like cluster which seems to constitute the previously unidentified center of the Great Attractor.

The innermost part of the Milky Way where the foreground obscuration in the blue is tex2html_wrap_inline482, respectively HI-column densities tex2html_wrap_inline484 remains fully opaque. In this approximately tex2html_wrap_inline486 wide strip, the forthcoming blind HI-survey with the multi-beam system at Parkes will provide the only tool to unveil this part of the extragalactic sky.
