I'll be arriving from a Southwest flight for QF94 to MEL. I see the BNE Flight leaves at 9.20. I land slightly after 5pm, would I be able to checkin once that flight desk opens at 6.20?? I'll try to do OLCI but given this is an intl flight, I have my doubts.

What are my options? Don't think it makes a difference but I am in business.
