It took me a minute to find it, but this reminded me of research I'd previously heard of that also turns out to be from UNSW and in fact one of the same authors:

UNSW research finds solar can act as early bushfire warning system

While investigating on the effects of wildfire smoke on rooftop PV installations, University of New South Wales (UNSW) researchers have found that solar arrays, due to their sensitivity to smoke, could serve as an early warning detection of wildfires by providing temporal and spatial information on the presence and approximate concentrations of smoke.

So that's a silver lining to this problem.

Unfortunately, smoke concentration is high when wind speeds are low, so you could get a double-whammy of degraded solar and degraded wind generation. Usually the two are pretty complementary, so conditions where generation from both is reduced is something that needs to be addressed. Offshore wind power is less variable, so this might underline its importance, as well as generally spreading out generation and firming with batteries.
