Astroloma conostephioides
Astroloma humifusum
Here are two short lists of Australian Native plants suitable for coastal planting.
It would be best if you consulted a local native plant nursery catalogue to check on heights and drainage/soil requirements. For example, in our 320 mm rainfall some of these would be quite reasonable for a suburban backyard. However the same tree in an area of 600 mm rainfall could grow to be far too big for the same size yard. The ultimate height and spread of the tree needs to be carefully considered. It is an expensive exercise to cut down a mature tree and a great shame to do so considering the time taken to reach that height.
Front line Coastal (there would be others)
Acacia floribunda, longifolia, suaveolens,
Banksia ericfolia, integrifolia, marginata, serrata
Fugosia patersonii,
Hakea suaveolens
Melaleuca armillaris, halmatuorum,Second line coastal (there would be others)
Acacia notabilis, pycnantha, saligna,
Agonis flexuosa,
Banksia baxteri, grandis, prionotes
Bursaria spinosa
Callistemon citrinus and forms, viminalis
Callitris rhomboidea
Various casuarinas and allocasuarinas
Ceratopetalum gummiferum
Many Eucalypts
Lillypilly forms
Grevillea robusta
I was thinking about the list so far realizing that there are many plants which fit this category which I do not actually know apart from what I read in specialist books. There is great information available if it can be found. In most cases it is important to remember that these plants need to have good drainage. Raising the planting hole or the garden bed as little as 100mm (4″), will provide sufficient drainage.
More Plants for Dry Conditions prostrate to 1 metre high.

A list like this could have some surprising species. Drought tolerance is a subjective thing in a plant. It depends on the amount of natural rainfall, whether it fell in the usual time of the year for the area, whether the garden is mulched, what shade is available, protection from hot drying winds etc. It is easier to change the conditions in a garden than in a paddock. In general, if conditions have been average then these plants should manage 3-4 months of summer with little extra water. Of course if some water is available they will do better. One deep watering is far more beneficial than many light weekly waterings in any situation. Be aware that many Australian native species have a ‘quiet’ time during summer and manage on little water as a result. Excessive watering in this case is likely to kill the plants. It pays to know about the plants that are grown.
This list is intended for garden culture. These are some plants I know of. There will be many that can be added.
