For those not from NSW/ACT/Qld its not 1 match, its 2 games; as only 4 NRL teams travel to LASand the rest of round one is played back in Aus/NZ the following weekend.
There may be some other demo games but none that count for the premiership. Then a bunch of fan events and excursions with chances to meet players etc.
As they change the 4 teams each year (there are 7 t choose from, 18 next year), there are targeting different teams fan bases from the previous year; given for some fans they'd only ever afford to do it once.
Its not like Magic round where all 8 (will be 9 in 2027) games of the round are played in the one city.
