research some flight prices

Need someone to research and find me the cheapest flights between Melbourne Australia and any of the following countries for the dates 23 December returning 31 December. Let me be clear: I don’t need flight details to ALL of these countries, I just need to know the cheapest flight, and it can be to any of the following countries. I also do not want the flight to involve china air, china southern, air asia, or Scoot airlines. Ideally there would be only one stopover, and this would not be for too long. Flights to Portugal, France, Germany, Spain, Italy, Switzerland, Romania, Czech republic, Ireland, Luxembourg, Greece, Malta, Austria, Belgium, Netherlands, Sweden, Denmark, Norway
