Hello, 
My wife is travelling with our 2 young boys (1.5yrs and almost 4 yrs) from Argentina to Melbourne Australia with connecting flights in between. The issue we are having is that when she gets to Sydney airport she will have to check out and transfer from the international terminal to the domestic terminal to the catch her final flight home to Melbourne. The problem with this is that she will have multiple heavy checked in  luggage,2 kids, pram and carry on bags to juggle all while trying to get to the domestic terminal by bus within short space of time to get her final flight. Are you able to help with this situation?
