Work travel has taken me to Emerald, Blackwater, Mackay, Rockhampton, Brisbane, Longreach, and others. And I've vacationed in Yeppoon and Byfield. Although Queensland is home to beaches, rivers, mountains, and tropic rain forests, from what I've seen the majority of the territory is flat grassland. Very flat. Kansas-flat. That's my impression after multiple drives from Brisbane to Mt. Isa, and from Sydney to Mt. Isa.
Visiting the far north tropics of Queensland is on my "wish list." Our recent family holiday was originally scheduled to include time at Cape Tribulation, but the plan was altered because of the impractical travel logistics.
