Hello,
I will spend one day on Fraser Island starting from River Heads this August.
I am planning to arrive at Kingfisher Bay with the first ferry in the morning (6.45 am), walk both ways to lake Mc Kenzie and take the ferry back (5 pm), which should be around 24 km.
Does this sound realistic to you and is there better/safer options for a one-day hike on the island ?
