Picked up the last one at Aldi Maroubra this evening. May be $44.90 or $44.95 or whatever. Haven't bothered checking my store receipt but its basically $45. Dan Murphy's has it for $56 and the local independent had it for $50 (bought a case there before buying another at Aldi).
It seems they don't advertise the alcohol online, perhaps because not all stores sell it and there may be different lines at different stores. Not sure. Would be nice if they did though.
