RAAF Maritime aircraft consolidated to Edinburgh air force base near Adelaide, SA when 11 Sqn moved into P-3B's [replaced by P-3C's] from P-2E's then based at Richmond near Sydney. The other MR sqn, No 10, was based in Townsville. When it re-equipped with P-3C's from SP-2H's it too moved to Edinburgh. The rationale was to consolidate maintanance, training etc near a big city that was roughly equidistance to both coasts [east/west] and the top end. P-3's are regularly deployed to Butterworth, the ME [10 years] as well as other bases on an as required basis. P-8 and Triton will do the same....
The base had a number of large underused hangars as well.
ARDU operate from there and Woomera is just up the road too...
