I've been looking through the old, but still excellent, book on the Sabre and derivatives by Eric Morgan and I noticed something, the Orenda version fitted to the Sabre Mk.6 quite matches the Avon and Sapphire in the Australian Sabres and Navy Furies, respectively, without needing the higher airflow either requires. So, what if Australia had gone in with Canada on Sabre development and not had to do as extreme a redesign for their use? By the same token, imagine Orenda-powered Furies flying from RCN carriers.
I've often been enamoured of the John Blaxland idea of greater co-operation between Australia and Canada. We are both Dominions, of a similar size and have similar political outlooks, aspirations and views on most issues. However, in real life Oz always looked to first the UK and then later the US for its ideas, politics and defence materiale'. It was a shame really, as there were many opportunities which were missed and continue to be missed. If, after WWII, Canada had, had a more Pacific view in it's foreign policy and Australia a more Northwards view in it's, there could have been quite a meeting of views. Canada however remained firmly locked on the North Atlantic and hence Europe, while Oz looked primarily to Asia.
It might have seen greater co-operation in South Korea, acted as a brake on our involvement in Vietnam and seen greater co-operation in Afghanistan and Iraq. Blaxland hypothesised in 2002 a joint Canadian-Australian Brigade in Iraq in 2003. We both operated Leopard 1s, M113s. Canada decided to purchase Leopard 2s, we decided to purchase M1s. In the air, you have your aforementioned Sabre possibility. If we had both gone into the great white hope of the Canadians, the CF-105, it might not have been so easily cancelled. We did need a Mach 2 fighter at the time and the CF-105 was supposedly exemplary. Instead we ended up with the Mirage III and the Canadians with the F-104.
