through 1965; staff moved in on 19 December 1965. With the new Bickely site complete, in 1967, Harris oversaw the installation of a meridian circle telescope at the Observatory as part of an expedition by astronomers from the Hamburg Observatory in Germany. The expedition worked on the international Southern Reference Stars program that resulted in a revised, larger and more accurate meridian catalogue of the Southern Hemisphere: the Perth 70 meridian catalogue. In 1970 Harris was successful in forming a dedicated Perth Observatory Meridian section to assist the German expedition in their work. After the German expedition left over the 1971/72 Christmas/New Year period, Harris successfully negotiated the loan of the Hamburg telescope indefinitely and obtained funding from the Government of Western Australia to increase the Meridian staff numbers. This Perth Observatory Meridian team continued and expanded on the German expedition work, resulting in the Perth 75 meridian catalogue. In 1967, Harris worked with the University of Western Australia to install a telescope at the Observatory that was built and used by the University of Western Australia staff and students, as well as Perth Observatory astronomers. Harris then moved the astrographic telescope, which had been in storage since August 1963, to the new site after arranging its refurbishment; the telescope recommenced observations on 29 March 1968, taking second epoch photographic plates for proper motion studies. In 1968, the Lowell Observatory of Flagstaff Arizona USA, located a Boller and Chivens telescope at the Perth Observatory as part of the International Planetary Patrol Program. The program was designed to collect 35-mm format photographic data on the atmospheric and surface features of Solar System planets, mostly Mars, Jupiter and Venus; Harris was to be a regular observer outside his normal daytime Government Astronomer role. Harris was successful in increasing the technical and astronomical staff numbers at the new Bickley Perth Observatory as its role moved to that of more of a scientific function, however Harris also restarted the public tours on 23 October 1966 and maintained the provision of information services to Western Australia. Harris also continued time and tide services for Western Australia, however as had been the case in 1908 for Meteorology, the move saw seismic monitoring activities being relocated to Mundaring under the Commonwealth Government control. Harris was responsible for the August 1973 IAU Symposium No. 61 in Perth on "New Problems of Astrometry". Like his predecessor, he died at
