I will be arriving on QF016 from Los Angeles at 7:15 AM and departing to Cairns on QF782 at 9:30 AM. My bags will have been checked through from Toronto to Cairns. Do I have to collect my bags to go through customs and immigration in Brisbane? Is the train the best way to get to the Domestic terminal? Is it free? Is a little more than 2 hours for all of this sufficient? Thanks in advance. I'm a little nervous but trusted Qantas factors this into their connecting flight schedules.
