Actually I'd say we're well served for Aussie PGs at the moment.
Yes a PG is, for want of better terminology, the on-court "General", and yes I suppose if you look at that in its purest form, there is less onus on the PG to score himself. Martin is probably the best exmaple at the moment.
But the NBL has always relied heavily on import PGs, and as such preference was always given to guys who could also score.
I suppose you could break "Combo" guards into two categories.
The first is a SG who can also handle the ball reasonably well. He may run the point occasionally as a back-up, but also in the modern game and shorter clocks, you need more than one guard who can handle and distribute. That's precisely why JJ was sacked (twice). Beal and Lisch are just a couple of examples.
The second is a PG, who scores so well that he could play the SG role. Randle and Ware are the two current greats in that department. Cotton is also in the same category, being predominately a PG, but being recruited to fill the SG role.
There have been some great Aussie PGs over the years, and there still are. But the NBL has also relied heavily on imports, and I think that will continue.
Part of the issue, is that for many players, as you proceed upwards, you also move further from the basket. I remember reading of an NBA PG, who actually played centre as a kid. That's why many Americans thrive in the NBL. Guys who grew up playing as forwards, but aren't big enough to play as PF, or good enough outside to play SF, in the NBA, can come out here and dominate at PF. So at the periphery, you've got these uber talented little guys, who are just too small to play NBA, but they make awesome NBL PGs.
