Hi, I am requesting help from the experts please!!!

I am looking at the following flights.

CNS-BNE, BNE-SYD-LAX, LAX-JFK, LGA-STL-LAS, LAX-HKG, HKG-SYD-BNE.

TA tells me that I cannot stop in BNE, but I definately did this on same ticket two years ago, is this correct information or incorrect???

Thanks for the help in advance!
