Hello. I haven't been to SYD in a couple of years. I'm use to collecting bags in T1, dropping them off at QF domestic drop off, clearing security and being driven to T3 airside.
No more, right? I'm not sure what is the benefit of the Seamless service. Do you still have to take your bags on the bus from Int to Dom?

In this case I'm arriving on SQ at 10:25am and departing on QF (Sunstate) at 1:05pm.

Will I have to clear immigration/customs, collect bag, take T bus with bag, recheck at QF Dom T3 and clear security?
Or will at least there be a QF baggage drop in T1? It seems there is no way to clear security any longer in T1 and be transferred airside without bags T1 to T3 but at least hoping there is a way to get rid of bags in T1.

Thanks for the advice.

I am OWE if that matters which I suspect it doesn't.
