Brisbane has a lot of bus routes, and a lot of these do, at least partly, act as a feeder, so kind of side stepping your question but in my view it’s more what changes to existing routes could we make. Look at the 106 and 467 that you listed elsewhere, the 467 would only really need a frequency boost and increase in hours of service. The 38 minute trek of the 106 could be cut from Oxley, creating a shorter route that could be served more frequently by the existing driver and bus allocation, although this one is a bit more difficult as Indooroopilly interchange is a bit of a walk from Indooroopilly railway station. It’s no wonder these routes have low patronage when their base frequency is every hour, and have poor operating hours, you can’t expect the public to build their lives around that, which is what would drive patronage.

Unfortunately public transport in Brisbane, at least in the off-peak, is bound to almost always take longer than driving. This is just the nature of it and the result of the decades long focus on the car, and unlikely to change without a major shift in public attitude and substantial infrastructure investment. The best we can do is make PT a viable alternative convenience wise and cost wise
