Harriet Island is in the Bundaberg town reach of the Burnett River. This island is uninhabited by humans, and was inundated in the floods of 2011. It is 1.4 km long and 450m wide at its widest point.
Best known for boot-sucking mud, marauding midges and mosquitos, high kangaroo grass and the support for a road bridge across the Burnett River, this island is perfect for challenging terrain caches.
There are numerous ways to access the island, you could abseil off the bridge, but that may attract too much attention. You could parachute in but the bush may be an issue and you may attract too much attention. You could get there by water craft, but mudless landing sites are not that plentiful. Or you could swim (not recommended), or wait for a low tide and walk across. The main issue for walking is the mud, lots of mud.
If returning to the mainland on foot later than two hours after low tide, be prepared for a swim, or a deep crossing at least.
