Hi Wartim
We loved Ocean Beach at Bribie. Beautiful spot. We've booked to go back on the long weekend in October. The inland track was closed due to flooding. It's an easy drive up the beach from Woorim. Just need to avoid around the high tide for a few hours. Remember the mozzie repellent too as they're pretty thick in the late afternoon. I'm sure you'll enjoy a visit there.
Cheers, Benji
