Australia is definitely not a small economy. It's the 13th largest economy in the world and would find itself in the higher echelons of global middle powers alongside Canada.
Also, the UK and Australia are currently negotiating terms for increased freedom of movement as part of the their new trade agreement (
Australia trade deal set to increase freedom of movement downunder), so to say there is no appetite for free movement in those two countries is factually incorrect.
Up until very recently, the UK was completely incapable of forming trade agreements independently of the EU. The only way CANZ countries could do so was by forming a trade agreement with the entire EU, which was a big obstacle in and of itself. That's why the UK is now, after officially leaving the EU, negotiating new free trade agreements with Aus and NZ, and looking to build upon existing trade with Canada that it had through CETA.
With that being said, trade potential is definitely minimal and is by far the least compelling reason for a CANZUK alliance/bloc.
Absolutely incorrect. Ask anyone who has tried to live and work in any of the CANZUK countries and they'd tell you how much of a nightmare the process can be. There's plenty of room for improvement on the freedom of movement front between these countries, and you can see that playing out in the UK-AUS/NZ new trade agreements.
There's some truth to this, but there's a lot changing on this front. Yes, Canada absolutely has long way to go in improving its military. However, it seems to be making some good and long overdue changes to its navy that will help a great deal in expanding its capabilities.
Most notably, the new Canadian Surface Combatant, based on the new British Type 26 frigate which Australia is also basing its new Hunter-class frigates on, will have very impressive and versatile capabilities that will put a lot of other frigates to shame, and will allow Canada to project more power than it has in many decades. It will be a top-tier submarine hunter fitted with limited but impressive anti-air capabilities (for a frigate), new state-of-the-art anti-ship and anti-land warfare missiles (Kongsberg NSM), as well as long-range tomahawk cruise missiles (which will be the only navy outside of the US and UK permitted to operate this lethal missile). See
Canada's New Frigate Will Be Brimming With Missiles.
Interestingly, with an anticipated order of 15 ships, Canada will have significantly more of these impressive vessels than Britain (8) and Australia (9), and, based on current information, it will also have a more versatile and extensive set of weaponry than its counterparts.
The new Joint Support Ships will also help immensely to sustain blue water operations for long periods of time, a capability we've not had since we retired our 2 Protecteur-class support ships. The next big things we need to focus on is finalizing our new fighter jet procurement program and to start a submarine replacement program for our old victoria-class fleet.
In my opinion, the most compelling potential benefits of a CANZUK alliance lie in the foreign policy and defense cooperation arenas. Trade and freedom of movement would really only serve to underpin those corresponding benefits. CANZUK has really only come to the forefront as a result of the increasing power polarization on the global stage, namely between China and the US, and the need to consolidate power and influence with our closest and like-minded allies to safeguard our interests. While we'll always have close ties and aligned interests with the US and the EU, they are both too
different and too
powerful to be part of this alliance without dominating it, as well as too
unpredictable to ensure a strong cohesion. With the exception of New Zealand, CANZUK countries are all high-end middle powers (UK is a borderline Great Power) with very similar roles and geopolitical stances on the global stage, so it only makes sense to pool our soft power and hard power together for enhanced leverage in international matters.
