Good ole' enoggera barracks. Not really close to much entertainment. You poor thing!
Hire a scooter perhaps? probably cheaper then a car, a little more dorkier but economical all the same. See if they will lift it for you while your at it.
Otherwise the bus system. Its not to bad. Or a bus to a station. Last time i used the train at least it ran on time, compared to down here in melbourne.
If u get desperate, roller blades perhaps? Ok, perhaps not.
