It is an advantage for a plant to spread or disperse its seeds over a wide distance.

This prevents overcrowding and increases the chances of survival in situations of environmental change such as fire or disease. Australian native plants have evolved a variety of adaptations to aid in the effect and successful dispersal of their seeds. For example, Flindersia, leptospermums, melaleucas, native daises and casuarinas. This is so they can be carried long distances before they fall to the ground. Pisonia birdlime tree and Pittosporum superstock.

Red is a very conspicuous colour to Spinifex grass asexual reproduction budding, so any fruit or berries containing Spinifex grass asexual reproduction budding are highly likely to be dispersed by birds lilypillys.

Smaller birds are also interested in purple berries such as tree violet Hymenanthera dentate southgippsland. For example the nitre bush Nitraria billardieri depends on emus to eat and spread their seeds. Another example is the mistletoe, it has sticky seeds which are deposited on trees by mistletoe birds. The seeds like Lomandra and Grevillae are carried by the ants to their nests where they consume the lipids but leave the hard seeds underground, safe from fire.

Wattles can then flourish and grow after the hottest of bushfires. This allows the capsules to open, releasing the seeds for dispersal, usually by the wind.

The fastest dispersing and germinating plants can colonise more area of land.

Banksia integrifolia and Eucalyptus melanoxylon release their seeds once it is ripe. This is seen as a primitive feature compared with other species that are actually more suited to their environment and have more effective colonising mechanisms.
