It generally follows the old alignments of roads that were once used as our main thoroughfares throughout the country. These caches will take you down roads and tracks and through towns and settlements that the Main Roads Authorities of this country don’t want you to see for some reason. Some of the roads chosen are done so because of historical facts, street names or, deductions based on studying old maps has led me to believe that these roads are the original alignments. In some instances, some of these detours are simply taken because they are more interesting than the main road! Following this route, instead of bypassing some of the beautiful places this country has to offer, will be both interesting and enjoyable. Highway One - Harvey Siding is just off the Bruce Hwy on the old highway alignment. There is plenty of room for parking, even with a caravan. You are looking for a small Sistema container. Happy caching. 
That was the old cache that I adopted, but, circumstances have changed, The Gympie Bypass.
13th December 2019 - Black Friday
Because we are getting the Gympie Bypass from the southern entrence to Hervey Siding, The cache was right in the middle of the entrence onto the newbypass. With consulations with Main Roads, it was suggested that on the other side of the Bruce Hwy, between it and the rail corredoor would be best.
Now, one can enjoy both the trafic on the Bruce Hwy and also get to see, if one is lucky, two trains passing, right in front. Enjoy
