According to Boeing's web site, the "enhanced" 744's that Quantas bought are referred to as the "Longer Range 747-400". To be honest, I don't know if Boeing has officially given this aircraft an ER or LR designation. They are just referring to it as the "Longer Range 744".
Check out Boeing's site under commercial, then 747, then new 747 family. The "New 747 Family" to click on is just above the column of 747's.
