Heading south from Brisbane towards Sydney, planning to detour via Tamborine NP, then one of the three mentioned. We have visited Lamington (Green Mountain) before. Binna Burra and Springbrook Plateau both involve lengthy out and back detours, whilst Natural Bridge seems to be on a through route. We like to do hikes of 2-5 kms and enjoy viewpoints etc. Are Binna Bura or Springbrook Plateau worth the extra Kms?
