The easiest way to travel to Brisbane is by air. Brisbane Airport is a large international airport with plenty of connections. You can find Enterprise Rent-A-Car at Level 2 in the international terminal and P1 at the domestic terminal. Both are approximately a 20-minute drive from the city centre. Due to Australia's sheer size, other forms of transport are less convenient. For example, the train from Sydney to Brisbane takes around 15 hours, making flights a far more attractive option.
