Hi Rooti
I did this amazing tour in November 2013, you will have a wonderful time, firstly the weather as I went a month after you we were just into Spring and the weather was fine throughout, not much rain at all and not too hot, perhaps in the dessert when you get to Alice Springs and later in Sydney and Melbourne but it was all manageable and not over hot, Cairns was a little humid but take your raincoat anyway, Jetlag wasn't too bad going but you will feel a little strange that first night but after that you'll adapt, we flew via Singapore but you may be going via Dubai, I didn't do any stopover, Aus is not cheap so you may need to budget quite high maybe around 600 to 800 £ but then again it all depends if your purchasing cuddly Koala bears and Kangaroos like I did
Perth - Freemantle and swan river cruise is a must - I didn't do the other excursions offered there as I was meeting friends but its nice along the water front area very close to hotel if its still the Travelodge - the TL not like ours and have huge rooms
Alice Springs - I did the western Mcdonnell Ranges as an extra was very good and the bush bbq was ok nothing special but glad I did it as you get to try your hand at boomerang throwing and get to see your first wild kangaroos, on the other night in AS a group of us walked into town for a meal, well worth the venture about a 15 - 20 min walk dined at Bojangles bar then took a taxi back
Ayers Rock - the sounds of the silence dinner was a memorable experience under the stars and seeing the rock at sunset and sunrise
Cairns - The Great Barrier Reef was very memorable, went out on a catamaran, you get the choice of staying on green island or continuing onto the outer reef if your a snorkeler, there is plenty to do on GI and of course you have lunch and a chance to snorkel there if you wish, didn't do Daintree as wanted a day of rest to look round Cairns, loved the Rattle n Hum bar but did the Kuranda railway which is a MUST, you can only book this out there but all the trips you could pay on arrival if that's what you prefer see who's doing what, you'll get the opportunity from your TM as you go
Sydney - the harbour cruise another must do as in the Blue Mountains which is another fab trip includes visit to Fetherdale wildlife park on the way, very enjoyable, you'll take lots of pictures everywhere so take plenty of memory cards or one 16 or 32 gb card, depends if you do any videoing - lots to see around Sydney and lovely parks - take a walk back to your hotel after cruise or do the harbour bridge climb, a few of us also took the ferry over to Manly beach one day was very nice saw loads of surfers
Melbourne was different again - take a walk along the yarra river see the MCG and the Tennis stadiums - also took to the eureka sky deck for fantastic views all over Melbourne -, I also took in a football match and watched some cricket at the MCG in one afternoon - take a tram ride or just go shopping - didn't do the optionals here as wanted time to chill and just wander round Melbourne, the final night Tramcar dinner was truly wonderful
you will find the flies are a pest but as your a month in front of us you may not encounter any but the only fly free places we visited were Cairns and Sydney but our TM got us some fly nets from the market in freemantle
so clothing I would cater for tshirts light cotton trousers light pullovers or fleeces for evening and early morning or for when on coach and a light raincoat as you may need it somewhere along the line, your not in summer by far but even spring days are much warmer than ours so enjoy and if there is anything else you'd like to know don't hesitate to ask and have a wonderful time
Regards
Dave
