Go on.

ATM I'd say avoid Ukraine

Our plan is 3 months away.

I don't fly well so our trip over looks like :

Adelaide / Singapore - Night in Singapore
Singapore / Dubai - Night in Dubai
Dubai / London

Week in UK ( all times subject to change ) I'm Welsh so going to Cardiff no matter what.

London / Amsterdam
Amsterdam / Budapest river cruise

Budapest / France
France / Spain
Spain / Italy
Italy / Greece

Emirates / Singapore night in Singapore
Singapore / Adelaide

This is the rough itinerary I'm working on

We are heading over for 5 1/2 weeks March/April based around a wedding in London.

Flying Qatar Airways;

Prague for few nights
London 10 days
Paris 6 days
Zurich 3 days
Milan 2 days
Venice 3 days
Florence 3 days
Rome 6 days
Doha 2 days by the pool before landing back in Adelaide.

All depends on when you “want” the long stretch on a flight. Both options are around 20hrs flight time each way total but obviously many people prefer the Singapore option for the 7hr stint home as you can the 13hr Europe to Singapore flight done, relax for a day or two and then short flight home.
Emirates is the better airline IMO but the 13hr flight back home does scare some people off.
Flights are dirt cheap in Europe but just beware some of the LCC land at secondary airports that are a looooong way out of town. I do prefer to either take the train or drive everywhere in Europe, get to see much more than just hopping from airport to airport.
Driving gives you luxury of just stopping in at pubs or restaurants along the way or seeing some unbelievable scenery.
