For Dida89
Thanks. I assumed bags would go through, just wasn't sure about eligibility for the bus. All 3 legs are on the one ticket. Hopefully all goes smoothly on the day!
If say, dep ADL - SYD - CMB, is: you show your passport at ADL, or PER/HBA/MEL/BNE, and then, they will issue you BP for the whole way, at SYD T3, go to gate 15, making sure you have all your HLO, at gate 15, take out the BP for the bus attendant counter person to scan, you scan BP, then go into the holding area, bus comes, you go down the slight steps, and then into the sardine can bus, over to T1, then through outgoing sec screening and immi, then to gate.
On a linked PNR, its not that bad, both for leaving and coming back to Aus, but if on unlinked PNR, ie, separate, that is where it can be troublesome.
