NSW TrainLink Discovery Pass comes with unlimited regional train travel anywhere within NSW, as well as to Canberra, Brisbane and (under normal circumstances) Melbourne for $550 / 6 Months.
If you purchase a “Premium” travel pass, you’ll be entitled to book First Class where available. Considering this only costs a little more than the Economy pass, it’s well worth buying a Premium pass.
Another key benefit of the Discovery Pass is that you can cancel without penalty if you need to. With the uncertainty surrounding regional travel at the moment, this could be useful if you need to make last-minute changes.
