As the wind changed to North East, we decided not to stop at Pancake Creek and continue through another night, heading down to the Great Sandy Strait. This is a large area of very shallow water and many sandbanks, between the main land and Fraser Island. Fraser Island is the largest sand island in the world at 1840sqkm (120km long). It was a major logging centre area, but now is mostly national park, catering to the 4x4 and camping enthusiasts, where there are miles and mile of tracks, most of which are on the beach, requiring low tide driving.
Its not only the 4x4’s that need to watch the tide.  Our first port of call was the marina at Urangan, but we had to slow right down, bobbing around until first light, so we could enter the channel and navigate to the marina. It was a quick but pleasant stop. Some of our more sophisticated Australian friends had warned us of the “Bogans” in Urangan ,  teasingly calling it  “Bougainville”   A bogan being similar to a redneck.  Well,  I have met some pretty nice rednecks in my life, and now I can say the same for the bogans at Urangan – they could not have been more friendly.
We borrowed the UTE from the marina for a few hours and drove along the coastal towns of Torquay, Scarness, Piabla and Mt Vernon.  We were amazed at how many houses there were out here, considering there is very little industry except tourism and fishing. Again we were impressed by the facilities offered to the Australian recreational fisherman.  Here is an example of a stunning slipway, FREE, albeit with a lot of rules.

From Urangan we crossed over the flats to Kingfisher Bay, main gateway to Fraser island. The car barge comes over 5 x a day, dropping off holiday makers. Next morning we took the dinghy over to the jetty and had a pleasant walk around the eco resort. There were more signs – some warning of aggressive wild dingo, but we did not see any.

We had been fretting over our next passage. We had to get across the skinniest part of the Great Sandy Straits, down towards the Wide Bar – entrance to the ocean.  This is a notorious stretch , with sand bars that are continuously moving, and tides that enter the straits from both sides. Running aground is a very real risk. The trick, is to ride the flood down to the shallowest part, where the tides meet,  and then ride the ebb tide down to the other side – a trip of about 14nm.  All good and well, except our High tide was at 7pm – and you cant move through the shallows in the dark.
As luck would have it, Mike heard 3 motor yachts talking on the radio, heading down at about 4pm. They knew the route and calculated that there would be enough water to cross from mid-tide, and we joined their convoy. However, quite soon into the route, the head boat warned us they we were not going to make it. Their draft was 1.8m and they were nearly touching, and our draft is 2.1m. So we stopped, idling around waiting for more tide. Again we were lucky when a heavy fishing boat (draft 2.3m) came along, and told us he had been doing the passage for 20 years and we could tuck in behind him. And the slow crawl began, weaving our way through the markers, sometimes seeing only 10cm under the keel, but not once did we run aground. Thank you mv CARLO. Just as the sun was setting, we made our way into Garry’s anchorage, for a well deserved rest.

This chart shows only the most complicated path, through middle,  shallowest part, each peg represents a turn.
Tomorrow we have a new challenge – At first light we need to get 15nm down the river, to arrive at the Wide Bay Bar in time for the high tide bar crossing. However the forecast is good, and we don’t anticipate any problems.
