February is one of our hottest months. Whether that's " too hot" for you, only you will know.

The main concern I have is that you're cramming too much into your time - what if the one day you've allowed for the Great Barrier Reef is wet/windy/ you just don't feel like going?

Suggest you have a look at flying times and factor in an extra 60-90 mins + travelling time to & from your hotels for each flight.

Unless there is some hugely compelling reason, I can't imagine why you would stick a trip to Fiji in the middle of your Australian trip. Do it on the way in or the way out I you can make the flights work.

Blue Mountains & Jenolan Caves in one day is too much in one day to do either justice in my experience.
Like temperatures, " worth it" is dependent upon your interests, experience & expectations - not something anyone else can really judge for you.

I have never quite understood the allure of the Blue Mountains. I drive past them all the time so I guess I am immune. If you've seen other magnificent rock formations I would give it a miss.
