Australia, New Zealand & the South Pacific - MEL - Where to wait?

Can anyone suggest somewhere my mom can wait for about 90 minutes until my flight arrives? She'll be arriving on QF at 7:55am and I'll be arriving on NZ at 9:20am. (Both flights are international arrivals.)

She'll have one checked bag and a carry-on in tow, and will probably need to sit and rest for at least part of the time. (On a good day, 90 minutes of walking and standing is near her limit, and after traveling for ~24 hrs I know she'll be tired.)

Thanks! :)

Yes I think that's the best thing to do. From the arrivals hall go back upstairs and there are some coffee/eating places next to the international departure gates. There are other places at either end of the terminal building where the domestic gates are as well, but probably the international section right in the middle of the terminal will be easiest to find and to meet up.
