You could try using VPNs etc like the posters above suggested op, but a better solution would be to use alternate exchanges(Fiat or Crypto) that are permitted in your country in my opinion.

I disagree. Did you forget exchanges like Smarkets, Matchbook etc? Their liquidity is pretty high too when compared to Betfair though I do know that Betfair is the exchange leader and that won't change anytime soon.
