Looking For A Dataset Regarding Australian Businesses Affected By Rainfall

I was looking in the energy, solar, and public transport sectors for publicly available datasets and trying to correlate them with the weather and rainfall datasets from the Bureau Of Meteorology (http://www.bom.gov.au/climate/data/index.shtml?bookmark=136&zoom=3&lat=-32.5355&lon=147.74&layers=B00000TFFFFFFFTFFFFFFFFFFFFFFFFFFFFTTT&dp=IDC10002-d).

But the correlation between number of passengers in public transport and rainfall seems to be weak across the few states that I looked at (NSW, ACT, QLD), as are the correlations between rainfall and demand for electricity as well as the correlation between demand for electricity and weather, demand for electricity in peak, off-peak times. I’m guessing because if its cold weather people will just turn on their heaters and in hot weather their ACs. Similarly, with population increases it would make sense why rainfall doesn’t affect public transport much.

So, I was wondering if anyone knew of any public datasets where I can make a somewhat strong relation with rainfall and revenue/or something similar. Maybe retail and restaurants, but they don’t really have their datasets out on display.
