Internationally it's not to bad , but certainly by Aus standards it's disappointing.
True , I draw my comparisons with most of my NFL and NBA experiences. For instance I went to the Houston Texans , from downtown you had 3 reasonable options from downtown which is 8miles south of downtown Houston..
1.Tram it from downtown . 1 line and ran regularly and was cheap.
2. Park at the stadium . Min $30.
3. Uber, designated drop off and pick up points . 100s of ubers just waiting there to collect you after the game. Fast and efficient with out the Sydney style scrum to get out of the stadium precinct.
Though Brisbane sets the benchmark of any stadium I've been too. Great efficient free transport to and from the stadium to all the major westfield shopping centres in Brisbane.
In comparison Sydneysiders are required to take 2 trains which just ruins the fan experience. Not to mention driving the route is hellish no matter the time or day.
