Does anyone know how long you need to connect from international (arriving on Etihad) to domestic with luggage and probably requiring assistance? Mum can walk a short distance, slowly, but would need a buggy or wheelchair. And how would I go about arranging assistance bearing in mind I'll be waiting in Adelaide? Thanks.

ETA: having looked at schedules, I guess what I am asking is whether arriving in BNE at 17.50 and leaving on the Qantas flight at 18.45 or the Virgin flight at 19.15 are feasible. I suspect I already know the answer :-(
