Air nz is a total combined weight of 46kgs for 2 bags but no more than 32kgs per bag if that makees sense. This will work well as we are taking the strollers and I'm going to make a special bag so the can go in the one bag together and then the left over allowance can go into the suitcases

, but you shouldn't have a problem in Sydney with your luggage.
. I remember seeing them years ago, for the first time thinking "they are suitcases, not carry on bags" it is quite funny when you see them. But Qantas doesn't seem to have such generous cabin baggage allowance.
Because the allowance is so so so large compared to ours the overhead lockers fill really quickly. Fortunately for us it was only a short flight LA to Vegas, but we had to put our carryon under the seat in front the whole way. Some others had to "gate-check" theirs which meant it ended up underneath.
