Quick answer
For most Australians, CoinSpot is the direct Swyftx upgrade. Once you switch to CoinSpot Markets (0.1% flat, no volume requirement), you're paying 6× less per trade than Swyftx's default 0.6%. CoinSpot has more coins (490+ vs 440+), 24/7 Australian-based live chat that outperforms Swyftx's support, and Mazars-audited proof of reserves that Swyftx doesn't publish.
For SMSFs, active traders, and trust-conscious users, Independent Reserve is the stronger choice. Swyftx has ISO 27001 and Fireblocks custody, but IR has 12+ years hack-free, IG Group backing, MAS licence in Singapore, and KPMG-integrated SMSF tax tools. Different product, different trust ceiling.
Note: Swyftx's mobile app is legitimately better than most competitors'. If your issue with Swyftx isn't the app itself but fees or specific tools, you can solve those without giving up UX by staying but adjusting how you trade.
