I will be staying for 3 weeks (Broadbeach/Surfer Paradise area). I will not have a rental car so will be relying on buses. Is the Go Card open to tourists? If so, is it worth purchasing a card to save you the hassle of finding the individual fare? Are they easily purchased or do you have to visit a bus depot/special outlet? I will check out the website but am keen to know any tips from regular users. Thank you for any advice.
