I assume that XT means tax but could not figure out the other two.
They are all taxes:
YC = Customs Fee
XY = US Immigration/Naturalization Fee
XT = Combination Tax - i.e. XA (Agriculture), XF (Passenger Facility Charge),
US (Transportation Tax), AY (Security Fee) ZP (Flight Segment Tax)
Note: Combination Tax is used because I believe a fare ladder on a ticket only support 3 different tax entries but Uncle Sam (and in your case the Australian government) collect more than 3 different types of taxes.
SYD, for example, collects Noise Levy Taxes and Passenger Service Charges, while the Australian government collects an Air Passenger Ticket Levy and a Goods and Services Tax. I'm thinking the XT your paying is probably a combination of 5 or 6 different taxes.
