yes, i believe that is correct, qf announced an order for 6 additional of type around the end of august and they will come on line late this year/early next year i believe.
as for the routes they seem to be employing them on the secondary leisure markets, into cooly, rocky, hobart/launy etc.
it seems a foregone conclusion that when the 146's become history that the 717 will be the sole jet in the qflink fleet.
