Enchylaena tomentosa (Ruby saltbush)

Ruby saltbush is a very adaptable native groundcover which grows in tropical, subtropical and temperate areas of Australia, in full sun and partial shade and, being a saltbush, it's very drought tolerant.  It has also been shown to attract beneficial predators and for that reason it's grown in market gardens which has resulted in reduced use of pesticides (see Gardening Australia 13/10/2012).  Ruby saltbush also has small orangey-yellow berries which are edible, although having tried them myself I can say they don't have much flavour!  It seeds quite readily so, in time, you can have quite an area covered by them if you wish.  Or give plants to friends for their vegetable gardens.
