HAve a fun trip
150aeros
Firstly have a fun trip, and enjoy yourself. That includes NOT having a TOO MUCH of a concern for the WX.
People have been flying through the TOP of OZ VFR for many years, and doing it very safely in this time of the year. You show great AIRMANSHIP for making the request and getting the LOCALS knowledge, this is an atribute that will serve you well. Don't worry about your hours, your attitude is very good.
The posts above are good advise, but don't think that flying any other time is BAD or DANGEROUS. The facts are that MARCH is late wet season, storms do exist, but like every where else in the world this can change from day to day. Some days you will not have a good run and may have to make the decision not to fly, others it will be plain sailing(flying). The moral is you can't really predict it so don't be too concerned and take it as it is on the day. Use your knowledge, ability, skills and attitude to make the decision at the time.
It is my advise that you will have a good trip, and that you will not have any major concers when you get up there. But that you will use your HEAD and think about things as you go. You will learn a lot and you will have some great fun and experiances to boot. I recon that you will have more trouble with the Restricted airspace than the WX.
I have been flying (untill two years ago) in the Territiory and NW WA for over 5 years, almost all of it VFR and at all times of the year, infact most flying is done in these parts during this time as the roads become unreliable. I can tell you from experiance that you will not have any problems, and hay, if you do, you will find a really great bunch of people in the towns and at the airfields who will help you whih whaterver they can.
Again have fun and don't let the WX worry you too much.
A wise old person once said, "It's better to be down on the ground wishing that you were up in the air, than bieng in the air and wishing you were on the ground".
That is one of many pearls of wisdom, the trick is to lock then all away and use them when the situation requires.
Have FUN.
Sorry mate I added this later ;
The vis is actually pretty good at this time of year as the wet has reduced the smoke and haze. lots of green everywhere. The KAKDU falls are in full flow and some spectecular ones through the Kimberly as well.
Very hot in the mid latitudes (Broom down to Shark bay and on the east coast in QLD) with lots of thermal turblence. I hate turbulence and try to go as high as possible, though at Alice Springs you will not be able to go high enough, so go high and just relax the best you can.
