Weeds because: They push out native plants, and dry out to become dry fuel for hot fires. They spread easily through wind and water and prickly seeds can attach to people, animals and cars.
Methods for control
Slash tall, dry plants. These will green up in a few weeks and be easier to spray.
Slash & Burn
If the plants have unripe seed, burn slashed areas to stop seed ripening.
Reduce plant material and reduce the heat of the fire.
Spray when plants are small & green. It reduces herbicide use and off-target kill.
Handpull where there are lots of natives.
Use native grass seed to out-compete the weed.
Dont Spread Seeds!
Seeds can be spread from muddy car tyres, shoes and car radiators. Prickly seeds can attach to clothes and swags. Check when leaving sites that your not taking weed seeds with you!
