I'll definitely be looking at the Westpac option then.
But will wait for a bit for the dust to settle, as recommended in this thread.
Whether Westpac is an option depends on your requirements as I mentioned.
Priority Pass is not a Koru replacement, and is more suited if you're traveling in Asia or Europe on airlines that don't have their own lounges. I'm pretty sure Westpac also only offer the Standard Plus membership which gives 10 visits per year.
