Economy Light for Au's - baggage allowed for whole party?

Hi - a question on AU benefits when in Economy Light.
we have a last minute budget trip coming in late January (NYC to LHR) and have just booked 'Economy Light', which was on super-sale. As an Au I can reserve seats, and get a checked bag - the question: does this apply to my partner and child as well? (all on same booking)
I can reserve seats for all 3 of us, so it seems that benefit apply to everyone in the party, but does the free Au baggage apply to each member of Au family as well? Worth knowing beforehand!
Thanks!
