Good description Jaba, and thanks for that appreciation of the conditions in that area.
A long time ago, about halfway through my first 10 years without a instrument rating, I was in one of Don Milroy's Cherokee 6's on the way fom Rocky to Brisbane to pick up a load of Telegraphs. The weather over the hills west of Maleny and at Kilcoy was all storms and rain so much so that I couldn't get though the valley to the Glasshouses, and I went back to Kingaroy and rang the boss. The papers were run out to me there ( the van driver got a smashed windscreen on the way out, so he wasn't happy either....)
When going from here almost due south to Watts Bridge sometimes, my track goes just west of Borumba Dam, over the Amamoor forest where the Gympie Muster is held, and the Tiger Country that is the headwaters of the Mary. Its very timbered, rugged, and gets a high rainfall that helps give the river some flow. Not many clearings for a place to go should my only motor fail. I stay a little higher unless there is something of particular interest, and give it a wide berth with any weather. That said, I don't feel officialdom should get in the act and declare it a no-low-fly area like Carnarvon Gorge.
On the Monday, a local young RAA Instructor who also has a Private licence, hired a 172 that had been IFR, left with two girl friends to drop them over to Toowoomba, but came back because of weather on his track. Good call. He drove them over later. I offered to IFR charter them over in the Navajo but it was declined because he wouldn't be flying and because of the cost.
Experience is not only about weather type, but learning where it can affect you the most, and learning where the Tiger areas are is a big part of that. A little extra fuel (without going overboard) to bypass them can be a boon for an easier flight.
