At Brisbane Cultural Centre busway station, how do you know where on the platform to wait for a given bus?

The Cultural Centre busway station is located on the south bank just over the river from the city centre, and is served by a huge number of buses. It's also very busy, both with locals and tourists who've been visiting the nearby museums / galleries / waterfront walks. It only has one platform in each direction, and space for about 4 or 5 buses to pull up at a time.

There are various electronic display boards up along the platform, which all say something helpful like "refer to the printed timetables". The timetables tell you when buses are due, and (roughly) where each bus line goes to, but nothing about where along the ~150m platform you need to be to catch a particular bus.

Is there any way to know where along the platform you should be waiting for a given bus? I saw a few people waiting at the arrivals end who waved frantically to flag down their bus, then ran to where it stopped. However, I saw others just sitting at seats by one part of the platform, who just stood up when their bus came and were in the right place. Fairly sure I also saw someone miss a bus by being in the wrong place, but I'm not certain...

Is there an order to where along the platform a given route stops (like at King George Square busway station), or is it just random and you have to keep you eyes open + run?
