No aircraft fly from Sydney to London, they all have to fly to a stopover city enroute. So the answer becomes very difficult as you get off one aircraft & some time you board a different aircraft for the next leg of your trip. If you want to find which airlines have London as a destination go to the Sydney Airport website and click on International Departures. You willfind that many airllines team up & use 1 aircraft with different flight codes. British Airways & QANTAS use a QANTAS plane to Bangkok then you might be on a BA flight form Bankok to London. There are 3 or 4 flights a day from Sydney. Thia airlines have 2 flights a day to Bangkok but when you get to Bangkok there are more flights to London so you can stay over & get on the very next plae to London. Not a good answer to your question I know, but this is how it is, when QANTAS start using the 777 200LR there will be direct flights one day.

Depending on the conditions you signed off when you purchased your ticket, and the reason for changing your flight, you will only be refunded the agreed amount. BA and Qantas are airline partners so BA may be more forgiving. I doubt it though.
