A southern hemisphere gravitational wave detector of sensitivity comparable to Advanced LIGO and VIRGO greatly improves the worldwide gravitational wave detector array. It creates a dramatic improvement in angular resolution, improves the statistical confidence of candidate events and enables improved discrimination against noise. This enables better distance estimates for inspiral events, allowing unambiguous optical identification of host galaxies for about 25% of neutron star binary inspiral events. AIGO is proposed to be similar to Advanced LIGO in optical configuration. The isolation and suspension systems will be down- selected from the stiff Advanced LIGO design and the soft systems developed at Gingin. The project is planned as an international collaboration. This talk will summarises the science benefits of AIGO and report the current status of the AIGO proposal, proposed international collaborations partners and management plan.
