I would second the advise re: the plane. We went via Qantas to Sydney in March on the A380 and it was wonderful. We then came back from Sydney to London on BA in a 747. The BA plane was terrible, it felt old and small compared to the A380. Important when trying to change nappies. We were also far from impressed with the BA service. 1.5 hours to check-in at Sydney airport. I was nursing the baby during a meal so I asked if I could have it later, after feeding the baby I asked for the meal, at first they said no but eventually gave in. On the second stage of the flight we were served last again and at first they thought they had no more meals available, eventually they found something. They only provided one meal to our little girl (8 months) 20 minutes before landing at Heathrow - I had packed some food for her just in case which we had to use. One other mother travelling on her own pressed the buzzer three times for hot water for a bottle, no one came so she eventually went to get some herself, she was bumped on the way back and burnt her hand it looked terrible poor thing. I would only ever fly BA again for trips less than 3 hours long. The service from Qantas was wonderful, kept meals for both of us, 6 jars of baby food per flight, came by every couple of hours and asked me if I needed water etc.
