Thank you for the replies. Yes Anbell, I do reside in Aust (Tas). I have a VPN which I initially setup to trade tennis until Betfair noticed the discrepancy somehow.

They made it clear that its illegal to trade tennis markets in play if you live here, despite my VPN indicating I was in London.
Bookies are no longer an option as I have either made too much and been warned off by means of stake limits or told to go away due to overusing the magnanimous 'generosity' of bookies stake returns for selections running 2nd or 3rd. There is a cookie commonly used by bookies if they wish to check out the sites you use in order to dissuade matched betting, etc, etc. which led me to discover 3 at one point.
So now I load guardian daily, remove NSW and WA races then settle in for a low volume trading experience for the afternoon. I have discovered that when you have to wait 30-40 mins for the next race due to the turnover tax and NSW, WA 10% it seriously affects discipline and leads to foolish attempts to trade way before any pro trader would ever consider doing so. The most viable option I can see is to become nocturnal in order to trade pre-off UK markets.
