8. Issues Funding Current expenditure ~$12M p.a. Current funding ~$10M p.a. Depreciation of $2.7–5M unfunded Siding Springs site agreement $0.5–1M below cost Restructuring/relocation costs AAT nearing end of life as a National Facility (~10 years) Total cost of current operation $90M over 5 years Likely relocation of CSIRO Marsfield to North Ryde CSIRO/Canberra option not favoured AAO in CSIRO, ASA Perth July 2008

9. Pros of AAO in CSIRO Optical capability gains backing of $1B p.a. science organisation (legal, financial, property, political…) Straightforward solution for Govt., DIISR Synergies and efficiencies Consistent with CSIRO position on National Facilities in NIS Review submission Provides single governance structure for Australian national astronomy infrastructure Opportunity for coordinated advice on astronomy infrastructure – Australian Astronomy Advisory Committee Enhance positioning for SKA and future large optical facility AAO in CSIRO, ASA Perth July 2008

10. Cons of AAO in CSIRO Requires restructure Potential loss of AAO ‘brand’ Radio/optical competition for resources within CSIRO Distraction from ASKAP and SKA developments Increased CSIRO influence Long term role of AAL? AAO in CSIRO, ASA Perth July 2008

11. Challenging timeline DIISR leading development of viable options Round table workshop 17 July (DIISR, AAO, AAL, CSIRO, ANU) Aiming for preferred option by mid August Alignment with response to NIS Review Submission by DIISR for 2009 Budget AAO in CSIRO, ASA Perth July 2008
