Waves not in Gladstone directly but a short drive and YEP! Spent a year on Curtis island, Agnes is your best bet, I spent a few of my days off at the Tannum sands surf club. Depending on tides and weather activity there are waves out the front. log on to Gladstone Ports Corperation web page, they have a live surf cam of Tannum and Agnes , ( probably one of the best surf webcams in OZ)so you can check it anytime live from anywhere. One of my favourite places in the country, I really enjoyed my time over there, always plenty to do in that neck of the woods.
Check it out, might be waves there now!!
