Quite a few Asteraceae (daisy flowers) have highly aromatic foliage. One in particular is the introduced weed Dittrichia graveolens (syn. Inula graveolens) or Stinkwort and boy does it stink. No need to crush the leaves on that one and if you pull one up your hands hum with its odor for ages.

In the dryer interior, highly scented plants tend to be more common, which extends to many plant families. Most of these plants have glandular hairs that exude a sticky substance, which besides the objectionable odor are usually tacky to touch. I would say the main purpose of these glandular hairs is to deter grazing animals and in Australia besides current day macropods, the now extinct megafauna were probably massive feeders on the vegetation and probably simulated these plants defense mechanism.
