Not really - although they are really telling you nothing since coming in September is nice to get set for the southern harvest and coming in March is just about right to head north for their tourist season.. Australia has a split personality as far as climate goes. Northern half is perfect during the winter. We have travelled through the deserts and up in the Kimberlies and had no rain for 4 months and rarely any cloud either and temperatures are relatively mild. It isn't winter, but is called the dry season. Plenty of work up there then. That is when we meet the backpackers moving around across the northern third of Australia
At the same time, the lower half is experiencing a Mediterranean winter - cold wet and miserable relatively, but still possibilities for farm work as crop sowing happens early winter
In summer the northern half and the centre are not pleasant places to be - wet season in the north and scorching hot in the middle - and while a fair bit of the bottom is hot and dry it is tolerable because it is dry - and because over christmas is when the wheat is harvested and a lot of stone fruit and grapes are harvested so there is work to be had.

The middle third of Oz on the east coast is neither Monsoon Climate (two seasons, wet and dry) nor Mediterranean climate (4 seasons winter, spring, summer and autumn (fall to you) so itn't too bad all year around. That area is pretty much limited to the east coastal band between Sydney and Brisbane.

I'm sure that Harvest Trail site will explain it better than this. See https://jobsearch.gov.au/harvesttrail/help_harvest.aspx for hints for figuring out the timing of certain crops.

Also major fruit growing areas up north - Queensland and northern Western Australia but I'm not sure when major harvesting time would be.
Tasmania can be very cold in winter and really nice in the summer.
Like the US , Australia covers a couple of major climatic zones so there is no perfect time to visit the whole country. You are intending a long trip so just as we do in our RV in the US, you can just move to wherever suits you at the time.

BTW have you done any research into how Australian degrees are regarded in the US. I know your system of education (and politics ) are a constant source of bewilderment and amusement for us so it is very likely that the opposite is true, or more likely it is totally unknown.

The other consideration is that external students pay pretty high tuition fees in Australian Universities and while we can get very generous government loans to pay them, nothing similar would be available to you. I imagine their fees would be on the various websites - as would their entry qualifications
