Hotel Watermark Brisbane

I'll stay a Hotel Watermark in Surfers Paradise. How will I go to Brisbane for a day trip?
If you Please provide the most rapid.
Take the bus to rail Helensvale. they run at least every half hour along the road GoldCoast. the train is running every half-hour and 1 hour. You can go down to the south shore, if you want and walk along the river and the bridge stops from downtown, you can go up or down located south of Brisbane, Roma Street or Central. Buy your ticket at the station before boarding the train. you used to be allowed to buy ticket in the bus but I'm not sure if you still can. Trains run about an hour and a half hour. It is 3 minutes per hour or Past 3 minutes from Helensvale
