Hi we did dps melb syd and the melb syd part was domestic flight. Youc can usually tell by flight number and or arriving/departing terminal etc. Virgin advised us we didin't have to collect luggage at Melbourne that it would be forwarded on to sydney but this was not the case. We had to collect luggage and clear customs, then check in for domestic fight at dmoestic termainl. If you want to buy duty free on arrival it would be last chance before you clear customs.
Not sure what case is with darwin flight but if your flight from darwin to melb is an international flight still leaving from and landing at international airport than it would be a different scenario to above.
