Qantas have an award which takes Qantas points, which are Km based NOT miles (i.e. much easier to accrue) 100 k =60 miles approx.
31,001-50,000 km coach 130K Bus 195 K 1st 260K
50,001-70,00 Km coach 150k, Bus 225K, 1st 300K
Now QF have pretty good routes, and NO r-t-w rules need apply .. i.e you can backtrack if you wish, as long as you do not go thru point of origin.
They may offer same deal for less "mile" points via One World?
