The double Island anchorage is not great so if you were waiting for a weather window you would be staying in Mooloolaba. If you were caught out at Double Island Point the trawlers use the western side of the bay so that is an indication of what is best, if you anchor in the eastern end it looks better but in reality the swell curls around the point and you an end up beam on to the waves. Because you have to leave from Mooloolaba the trip to Bustard Head is quite a long way. The bar has moved quite a long way north so it pays to check the latest way points with Tin Can Bay. The new entrance is workable in most conditions.
Going outside you should keep clear of the long sand spit north of Fraser cos there are strong tidal currents through channels in the sand that whip up confused cross seas. And watch out for Wolf Rock off Double Island point, it's easy enough to sea but it's definitely not the time to be down below brewing a cup of coffee.
God advice there Phoenix.
There is the Breaksea Spit Light well north of Fraser. Pass north of it and you should be fine in most conditions.
If you want to head over to Bundaberg from Fraser it is possible in the right conditions to pass south of the light between it and the spit. The right conditions are 1. A slack tide, preferably high. 2. Calm conditions. I wouldn't do it in more than a 1 metre sea. 3. Daylight. In daylight you can see the white sand 40 to 50 feet below you and start doubting the accuracy of your sounder.
Even in perfect conditions, dead flat calm, you can see the ripples and glassy surfaces of the water where the overfalls are. It is just spooky.
If you do this passage it will save you about 12 miles going to Bundaberg.
