Millman's observations about the lack of Australian events are interesting, and I'd agree that it isn't doing much to encourage new players to break through.
However, that doesn't mean that new players should accept the situation at home.
If it is financially possible (through private sponsorship, family finances, TA backing etc), maybe some players should train in another country? E.g. if they move to the USA, they could access the USTA Pro Circuit.
Another potentially less expensive alternative is that a player decides to travel non-stop for 6-12 weeks on the challenger/Futures circuit.
With a base in Australia, the player could target events in Asia - there are many of them, and the draws are often a lot weaker, providing a good opportunity to earn cheap points and move up the rankings...
You don't understand how it is in Australia. TA are very rich and they only fund a few and stop it. Matosevic made it, but look how long it took. Funny thing is now he gets funding whereas when he really needed it, they weren't around. Travelling 12 weeks straight you do know that costs money, it's the chicken and the egg thing. Millman would have to win 3 or 4 of these events to make cash. He wins matches and loses money yes that makes sense.
You are not rewarding mediocrity increasing the money at Chall and Futures, considering it hasn't increased since the mid 80s and expenses have gone up majorly. It's pretty obvious.
