Cycling in Brisbane Australia
There are plenty of northside commuters on here who will be able to give you good advice, however here is my route to and from the city.
I would recommend the return route from the city on this strava activity as a good inbound route as well, but others may offer some fine tuning. I live at Carseldine, but you can pick it up from the Chermside area and see what you think.
My quiet route from the outer north to the King George Square via 7th Brigade Park, designed to avoid known issues like the Kittyhawk Drive intersection. I haven't been riding much this year due to a knee injury, but if you're keen I am prepared to accompany you if we can tee up a suitable day.
