Australian dilemma 2 - Daintree Rainforest or Atherton Tableland mountains?

• Daintree Rainforest or Atherton Tableland Hills?
• Are the Scenic Train / Skyrail between Cairns & Kuranda for over AUS$35 each worth it?
• Any thoughts about the Tjabukai Cultural Park?
  

If you've got any opinions about any of the above, please comment.
