Also just discovered that my favourite site for watching tennis, LiveScoreHunter is only showing ATP doubles matches.
I'm sure they'll show singles once the main draw starts.
No help for Brisbane, but Eurosport player is only £1.99 per month (minimum 12 months), down from £2.99 if you sign up by 3/1/13. They're showing some Hopman Cup, then AO. Also good for catch up.
Batz, I also spotted that Tennis TV was only showing WTA for Brisbane, but the link you mention is misleading. I hope you get a response.
