Sorry in advance if someone has asked this before and answered.

I'm flying soon with Qantas (and partners on a business round the world ticket(.

From reading the info online, I'm not entirely sure about whether what I planned on taking as checked on luggage will be accepted.

I have a decent sized backpack (designed to carry a laptop but it is big enough to have wheels and a expandable handle) and then have a smaller camera bag which is also a backpack.

I had hoped to fit the camera one inside the bigger one with a few other things bit after testing it, it wouldn't work.

I have taken the larger one as carry on to New Zealand before with no trouble but am concerned for this upcoming trip, they will not accept both.

I already have 2 suitcases I will be checking in so that isn't an option.

Do people think this will bee an issue? If it will be, I think I have a work around as the person I am travelling with is just planning on having a normal laptop bag as carry on so they should be able to take the other one. But if I can avoid this and have both with me, that would be my preference.

Thanks in advance for any advice that can be given.
